🎨 Anatomy

Component	Description
`Select.Root`	The root container for the Select component.
`Select.Label`	A label that computes the accessible name of the select. If not present, the display value is used instead.
`Select.Trigger`	A button or similar control that opens the select menu when interacted with.
`Select.DisplayValue`	Displays the currently selected value.
`Select.Popover`	A wrapper of the Qwik UI Popover component. It places its content above everything else.
`Select.Listbox`	A list that displays selectable items.
`Select.Item`	A selectable item within the Select.Listbox.
`Select.ItemLabel`	The item's label. If there is no value prop, this is the item's value.
`Select.ItemIndicator`	Allows you to render an icon or other visual element that is displayed next to the item's label whenever an item is selected.
`Select.Group`	Groups related items within the Select.Listbox.
`Select.GroupLabel`	A label that computes the accessible name of the group.

Why use a headless Select?

The native <select> HTML element encounters significant obstacles in terms of styling flexibility, consistency across different browsers, and delivering a seamless user experience.

Native Select pain points

Styling Limitations
Multiselect Complexity
Limited Typeahead Support
Inconsistent Behavior across browsers and devices

Native effort

The Open UI group is creating a stylable select element to address similar use cases as headless components.

However, since it is built on the existing native select element, its customizability and out-of-the-box experience may be limited, even with upcoming enhancements.

Passing data

To add data, use the <Select.Item> component inside of the listbox.

Basic example

Logged in users

import { component$, useStyles$ } from '@builder.io/qwik';
import { Select } from '@qwik-ui/headless';

export default component$(() => {
  useStyles$(styles);

  return (
    <Select.Root class="select">
      <Select.Label>Logged in users</Select.Label>
      <Select.Trigger class="select-trigger">
        <Select.DisplayValue placeholder="Select an option" />
      </Select.Trigger>
      <Select.Popover class="select-popover">
        <Select.Item>
          <Select.ItemLabel>Option 1</Select.ItemLabel>
        </Select.Item>
        <Select.Item>
          <Select.ItemLabel>Option 2</Select.ItemLabel>
        </Select.Item>
      </Select.Popover>
    </Select.Root>
  );
});

// internal
import styles from '../snippets/select.css?inline';

By default, the content inside of the <Select.ItemLabel /> component is the item's value.

Mapping over data

Logged in users

import { component$, useStyles$ } from '@builder.io/qwik';
import { Select } from '@qwik-ui/headless';

export default component$(() => {
  useStyles$(styles);
  const users = ['Tim', 'Ryan', 'Jim', 'Jessie', 'Abby'];

  return (
    <Select.Root class="select">
      <Select.Label>Logged in users</Select.Label>
      <Select.Trigger class="select-trigger">
        <Select.DisplayValue placeholder="Select an option" />
      </Select.Trigger>
      <Select.Popover class="select-popover">
        {users.map((user) => (
          <Select.Item class="select-item" key={user}>
            <Select.ItemLabel>{user}</Select.ItemLabel>
            <Select.ItemIndicator>
              <LuCheck />
            </Select.ItemIndicator>
          </Select.Item>
        ))}
      </Select.Popover>
    </Select.Root>
  );
});

// internal
import styles from '../snippets/select.css?inline';
import { LuCheck } from '@qwikest/icons/lucide';

You control how the data is rendered. Map over the data or render the items as you like.

Object example

Logged in users

import { component$, useStyles$ } from '@builder.io/qwik';
import { Select } from '@qwik-ui/headless';
import styles from '../snippets/select.css?inline';

export default component$(() => {
  useStyles$(styles);
  const users = [
    { name: 'Tim', status: '🟢' },
    { name: 'Ryan', status: '🔴' },
    { name: 'Jim', status: '🟡' },
    { name: 'Jessie', status: '🟢' },
    { name: 'Abby', status: '🟡' },
  ];

  return (
    <Select.Root class="select">
      <Select.Label>Logged in users</Select.Label>
      <Select.Trigger class="select-trigger">
        <Select.DisplayValue placeholder="Select an option" />
      </Select.Trigger>
      <Select.Popover class="select-popover">
        {users.map((user) => (
          <Select.Item key={user.name}>
            <Select.ItemLabel>{`${user.status} ${user.name}`}</Select.ItemLabel>
          </Select.Item>
        ))}
      </Select.Popover>
    </Select.Root>
  );
});

Passing a distinct value

Logged in users

The selected value is: null

import { $, component$, useSignal, useStyles$ } from '@builder.io/qwik';
import { Select } from '@qwik-ui/headless';

export default component$(() => {
  useStyles$(styles);
  const users = [
    { id: '0', label: 'Tim' },
    { id: '1', label: 'Ryan' },
    { id: '2', label: 'Jim' },
    { id: '3', label: 'Jessie' },
    { id: '4', label: 'Abby' },
  ];

  const selected = useSignal<string | null>(null);

  const handleChange$ = $((value: string) => {
    selected.value = value;
  });

  return (
    <>
      <Select.Root onChange$={handleChange$} class="select">
        <Select.Label>Logged in users</Select.Label>
        <Select.Trigger class="select-trigger">
          <Select.DisplayValue placeholder="Select an option" />
        </Select.Trigger>
        <Select.Popover class="select-popover">
          {users.map((user) => (
            <Select.Item value={user.id} key={user.id}>
              <Select.ItemLabel>{user.label}</Select.ItemLabel>
            </Select.Item>
          ))}
        </Select.Popover>
      </Select.Root>
      <p>The selected value is: {selected.value ?? 'null'}</p>
    </>
  );
});

// internal
import styles from '../snippets/select.css?inline';

A distinct value is when one thing is displayed to the user, but another value is passed to the item.

By adding the value prop to the <Select.Item /> component, a distinct value is created.

Handling selection changes

Logged in users

You have changed 0 times

import { $, component$, useSignal, useStyles$ } from '@builder.io/qwik';
import { Select } from '@qwik-ui/headless';
import styles from '../snippets/select.css?inline';
export default component$(() => {
  useStyles$(styles);
  const users = ['Tim', 'Ryan', 'Jim', 'Jessie', 'Abby'];
  const counter = useSignal(0);

  const handleChange$ = $((): void => {
    counter.value++;
  });

  return (
    <>
      <Select.Root onChange$={handleChange$} class="select">
        <Select.Label>Logged in users</Select.Label>
        <Select.Trigger class="select-trigger">
          <Select.DisplayValue placeholder="Select an option" />
        </Select.Trigger>
        <Select.Popover class="select-popover">
          {users.map((user) => (
            <Select.Item key={user}>
              <Select.ItemLabel>{user}</Select.ItemLabel>
            </Select.Item>
          ))}
        </Select.Popover>
      </Select.Root>
      <p>You have changed {counter.value} times</p>
    </>
  );
});

Use the onChange$ prop to listen for changes in the selected value. It provides the new selected value as an argument.

The example above increments a count when a new item is selected.

Forms

To use the select in a form, we provide a visually hidden native select element inside of <Select.HiddenNativeSelect>.

import { component$, useStyles$, $, useSignal } from '@builder.io/qwik';
import { Select } from '@qwik-ui/headless';
import { LuCheck } from '@qwikest/icons/lucide';

type FormData = Record<string, FormDataEntryValue[]>;

export default component$(() => {
  useStyles$(styles);
  const users = ['Tim', 'Ryan', 'Jim', 'Jessie', 'Abby'];
  const displayValue = useSignal<string[]>([]);

  const submittedData = useSignal<FormData | null>(null);
  const formName = 'my-example-name!';

  const handleSubmit$ = $(async (_: SubmitEvent, form: HTMLFormElement) => {
    const formData = new FormData(form);

    // multi-select example. (Don't use getAll for single)
    const entries = formData.getAll(formName);
    submittedData.value = { [formName]: entries };
  });

  return (
    <>
      <form preventdefault:submit onSubmit$={handleSubmit$}>
        <Select.Root
          name={formName}
          bind:displayValue={displayValue}
          multiple
          required
          class="select"
        >
          <Select.Label>Logged in users</Select.Label>
          <Select.HiddenNativeSelect />
          <Select.Trigger class="select-trigger">
            <Select.DisplayValue>{displayValue.value.join(', ')}</Select.DisplayValue>
          </Select.Trigger>
          <Select.Popover class="select-popover">
            {users.map((user) => (
              <Select.Item class="select-item" key={user}>
                <Select.ItemLabel>{user}</Select.ItemLabel>
                <Select.ItemIndicator>
                  <LuCheck />
                </Select.ItemIndicator>
              </Select.Item>
            ))}
          </Select.Popover>
        </Select.Root>
        <button type="submit">Submit my form!</button>
      </form>
      {submittedData.value && (
        <>
          <strong>You submitted:</strong>
          <code>{JSON.stringify(submittedData.value)}</code>
        </>
      )}
    </>
  );
});

// internal
import styles from '../snippets/select.css?inline';

The native select element is created when a form name has been given to <Select.Root />

Validation

import { component$, useStyles$, $ } from '@builder.io/qwik';
import { LuCheck } from '@qwikest/icons/lucide';
import { Select } from '@qwik-ui/headless';
import { useForm, required } from '@modular-forms/qwik';

type Users = {
  firstName: string;
};

export default component$(() => {
  const users = ['Tim', 'Ryan', 'Jim', 'Jessie', 'Abby'];
  const [, { Form, Field }] = useForm<Users>({
    loader: { value: { firstName: '' } },
  });

  useStyles$(styles);

  const handleSubmit$ = $(() => {
    console.log('submitted!');
  });

  return (
    <Form onSubmit$={handleSubmit$}>
      <Field
        name="firstName"
        type="string"
        validate={[required<string>('Make sure to select an option')]}
      >
        {(field, props) => {
          return (
            <Select.Root class="select" required>
              <Select.HiddenNativeSelect {...props} />
              <Select.Label>Logged in users</Select.Label>
              <Select.Trigger class="select-trigger">
                <Select.DisplayValue placeholder="Select an option" />
              </Select.Trigger>
              {field.error && (
                <Select.ErrorMessage style={{ color: '#D2122E' }}>
                  {field.error}
                </Select.ErrorMessage>
              )}
              <Select.Popover class="select-popover">
                {users.map((user) => (
                  <Select.Item class="select-item" key={user}>
                    <Select.ItemLabel>{user}</Select.ItemLabel>
                    <Select.ItemIndicator>
                      <LuCheck />
                    </Select.ItemIndicator>
                  </Select.Item>
                ))}
              </Select.Popover>
            </Select.Root>
          );
        }}
      </Field>
      <button type="submit">Submit my form!</button>
    </Form>
  );
});

// internal
import styles from '../snippets/select.css?inline';

The <Select.ErrorMessage /> component is used to display errors when the select is invalid.

To style based on the invalid state, use the data-invalid data attribute.

Descriptions

Provide more information to assistive technologies by adding a description to the select.

Logged in users

Select a user to see their profile

import { component$, useStyles$ } from '@builder.io/qwik';
import { Select } from '@qwik-ui/headless';

export default component$(() => {
  useStyles$(styles);
  const users = ['Tim', 'Ryan', 'Jim', 'Jessie', 'Abby'];

  return (
    <Select.Root class="select">
      <Select.Label>Logged in users</Select.Label>
      <Select.Trigger class="select-trigger">
        <Select.DisplayValue placeholder="Select an option" />
      </Select.Trigger>
      <Select.Description>Select a user to see their profile</Select.Description>
      <Select.Popover class="select-popover">
        {users.map((user) => (
          <Select.Item class="select-item" key={user}>
            <Select.ItemLabel>{user}</Select.ItemLabel>
            <Select.ItemIndicator>
              <LuCheck />
            </Select.ItemIndicator>
          </Select.Item>
        ))}
      </Select.Popover>
    </Select.Root>
  );
});

// internal
import styles from '../snippets/select.css?inline';
import { LuCheck } from '@qwikest/icons/lucide';

Component state

We can select an initial uncontrolled value by passing the value prop to the <Select.Root /> component.

Uncontrolled / Initial value

Logged in users

import { component$, useStyles$ } from '@builder.io/qwik';
import { Select } from '@qwik-ui/headless';

export default component$(() => {
  useStyles$(styles);
  const users = ['Tim', 'Ryan', 'Jim', 'Jessie', 'Abby'];

  return (
    <Select.Root value="Jessie" class="select">
      <Select.Label>Logged in users</Select.Label>
      <Select.Trigger class="select-trigger">
        <Select.DisplayValue placeholder="Select an option" />
      </Select.Trigger>
      <Select.Popover class="select-popover">
        {users.map((user) => (
          <Select.Item key={user}>
            <Select.ItemLabel>{user}</Select.ItemLabel>
          </Select.Item>
        ))}
      </Select.Popover>
    </Select.Root>
  );
});

// internal
import styles from '../snippets/select.css?inline';

The above example passes one of the item values "Jessie" as the initial value. As a result, the matching value is selected and focused.

Controlled / Reactive value

We can pass reactive state by using the bind:value prop to the <Select.Root /> component.

Logged in users

Your favorite user is: Ryan

import { component$, useSignal, useStyles$ } from '@builder.io/qwik';
import { Select } from '@qwik-ui/headless';
export default component$(() => {
  useStyles$(styles);
  const users = ['Tim', 'Ryan', 'Jim', 'Jessie', 'Abby'];
  const selected = useSignal<string>('Ryan');

  return (
    <>
      <Select.Root bind:value={selected} class="select">
        <Select.Label>Logged in users</Select.Label>
        <Select.Trigger class="select-trigger">
          <Select.DisplayValue placeholder="Select an option" />
        </Select.Trigger>
        <Select.Popover class="select-popover">
          {users.map((user) => (
            <Select.Item key={user}>
              <Select.ItemLabel>{user}</Select.ItemLabel>
            </Select.Item>
          ))}
        </Select.Popover>
      </Select.Root>
      <p>Your favorite user is: {selected.value}</p>
    </>
  );
});

// internal
import styles from '../snippets/select.css?inline';

bind:value is a signal prop, it allows us to reactively control the selected value of the select component.

We can also reactively control the open state of the select component by using the bind:open signal prop.

Logged in users

import { component$, useSignal, useStyles$ } from '@builder.io/qwik';
import { Select } from '@qwik-ui/headless';
import styles from '../snippets/select.css?inline';

export default component$(() => {
  useStyles$(styles);
  const users = ['Tim', 'Ryan', 'Jim', 'Jessie', 'Abby'];
  const isOpen = useSignal(false);

  return (
    <>
      <button onClick$={() => (isOpen.value = true)}>Toggle open state</button>
      <Select.Root bind:open={isOpen} class="select">
        <Select.Label>Logged in users</Select.Label>
        <Select.Trigger class="select-trigger">
          <Select.DisplayValue placeholder="Select an option" />
        </Select.Trigger>
        <Select.Popover class="select-popover">
          {users.map((user) => (
            <Select.Item key={user}>
              <Select.ItemLabel>{user}</Select.ItemLabel>
            </Select.Item>
          ))}
        </Select.Popover>
      </Select.Root>
    </>
  );
});

Programmatic changes

We can also programmatically change the selected value by changing the value of the signal.

Logged in users

import { $, component$, useSignal, useStyles$ } from '@builder.io/qwik';
import { Select } from '@qwik-ui/headless';
export default component$(() => {
  useStyles$(styles);
  const users = [
    { id: '0', name: 'Tim' },
    { id: '1', name: 'Ryan' }, // 👈 start with Ryan
    { id: '2', name: 'Jim' },
    { id: '3', name: 'Jessie' },
    { id: '4', name: 'Abby' },
  ];
  const selectedId = useSignal<string>('1');

  return (
    <>
      <Select.Root bind:value={selectedId} class="select">
        <Select.Label>Logged in users</Select.Label>
        <Select.Trigger class="select-trigger">
          <Select.DisplayValue placeholder="Select an option" />
        </Select.Trigger>
        <Select.Popover class="select-popover">
          {users.map((user) => (
            <Select.Item value={user.id} key={user.id}>
              <Select.ItemLabel>{user.name}</Select.ItemLabel>
            </Select.Item>
          ))}
        </Select.Popover>
      </Select.Root>
      <button onClick$={$(() => (selectedId.value = '4'))}>Change to Abby</button>
    </>
  );
});

// internal
import styles from '../snippets/select.css?inline';

In the above example, we've changed the selected value by clicking on the "Change to Abby" button.

Disabled items

This one is the disabled

Logged in users

import { component$, useStyles$ } from '@builder.io/qwik';
import { Select } from '@qwik-ui/headless';

export default component$(() => {
  useStyles$(styles);
  const users = ['Tim', 'Ryan', 'Jim', 'Bobbie', 'Joan', 'Jessie', 'Abby'];

  return (
    <Select.Root class="select">
      <p>This one is the disabled</p>
      <Select.Label>Logged in users</Select.Label>
      <Select.Trigger class="select-trigger">
        <Select.DisplayValue placeholder="Select an option" />
      </Select.Trigger>
      <Select.Popover class="select-popover">
        {users.map((user, index) => (
          <Select.Item
            key={user}
            disabled={
              index === 0 || index === 2 || index === users.length - 1 ? true : false
            }
          >
            <Select.ItemLabel>{user}</Select.ItemLabel>
          </Select.Item>
        ))}
      </Select.Popover>
    </Select.Root>
  );
});

// internal
import styles from '../snippets/select.css?inline';

Items can be disabled by adding the disabled prop to the <Select.Item /> component.

Disabled items are not selectable or focusable. They are also skipped when using the arrow keys to navigate through the items.

Dynamically adding users

A common use case is the addition of items dynamically. For example, an infinite scrolling list of users.

import { $, component$, useSignal, useStyles$ } from '@builder.io/qwik';
import { Select } from '@qwik-ui/headless';

export default component$(() => {
  useStyles$(styles);
  const users = useSignal<string[]>(['Tim', 'Ryan', 'Jim', 'Jessie', 'Abby']);
  const hasAddedUsers = useSignal<boolean>(false);

  return (
    <>
      <Select.Root class="select">
        <Select.Label>Logged in users</Select.Label>
        <Select.Trigger class="select-trigger">
          <Select.DisplayValue placeholder="Select an option" />
        </Select.Trigger>
        <Select.Popover class="select-popover">
          {users.value.map((user) => (
            <Select.Item key={user}>
              <Select.ItemLabel>{user}</Select.ItemLabel>
            </Select.Item>
          ))}
        </Select.Popover>
      </Select.Root>
      <button
        onClick$={$(() => {
          if (!hasAddedUsers.value) {
            users.value = [...users.value, 'John', 'Jane', 'Bob'];
            hasAddedUsers.value = true;
          }
        })}
      >
        Add Users
      </button>
    </>
  );
});

// internal
import styles from '../snippets/select.css?inline';

Clicking the Add Users button adds a couple new users mapped to the list. Taking this further, we could grab more data from the server and add it to the list, or even hitting a database to get more users.

Item Indicators

Logged in users

import { component$, useStyles$ } from '@builder.io/qwik';
import { Select } from '@qwik-ui/headless';
import { LuCheck } from '@qwikest/icons/lucide';

export default component$(() => {
  useStyles$(styles);
  const users = ['Tim', 'Ryan', 'Jim', 'Jessie', 'Abby'];

  return (
    <Select.Root class="select">
      <Select.Label>Logged in users</Select.Label>
      <Select.Trigger class="select-trigger">
        <Select.DisplayValue placeholder="Select an option" />
      </Select.Trigger>
      <Select.Popover class="select-popover">
        {users.map((user) => (
          <Select.Item class="select-item" key={user}>
            <Select.ItemLabel>{user}</Select.ItemLabel>
            <Select.ItemIndicator>
              <LuCheck />
            </Select.ItemIndicator>
          </Select.Item>
        ))}
      </Select.Popover>
    </Select.Root>
  );
});

// internal
import styles from '../snippets/select.css?inline';

We can add an indicator to the selected item by adding the <Select.ItemIndicator /> component inside the <Select.Item /> component.

This is useful for indicating the selected item in a list of items.

Multiple selections

Sometimes we want to allow the user to select multiple pre-defined items at a time. We can do that by setting the multiple prop to true.

import { component$, useSignal, useStyles$ } from '@builder.io/qwik';
import { Select } from '@qwik-ui/headless';
import { LuCheck } from '@qwikest/icons/lucide';

export default component$(() => {
  useStyles$(styles);
  const users = ['Tim', 'Ryan', 'Jim', 'Jessie', 'Abby'];
  const display = useSignal<string[]>([]);

  return (
    <Select.Root bind:displayValue={display} multiple class="select">
      <Select.Trigger class="select-trigger">
        <Select.DisplayValue>{display.value.join(', ')}</Select.DisplayValue>
      </Select.Trigger>
      <Select.Popover class="select-popover">
        {users.map((user, index) => (
          <Select.Item value={index.toString()} class="select-item" key={user}>
            <Select.ItemLabel>{user}</Select.ItemLabel>
            <Select.ItemIndicator>
              <LuCheck />
            </Select.ItemIndicator>
          </Select.Item>
        ))}
      </Select.Popover>
    </Select.Root>
  );
});

// internal
import styles from '../snippets/select.css?inline';

If we want to configure the multiple display values, we can use the bind:displayValue signal.

Something to be aware of, is the <Select.DisplayValue /> component will now display whatever you put inside of it.

Taking this a step further, one could combine the bind:value and bind:displayValue props together to create a custom widget that displays the selected values in a list of pills.

Logged in users

import { component$, useSignal, useStyles$ } from '@builder.io/qwik';
import { Select } from '@qwik-ui/headless';
import { LuCheck, LuX } from '@qwikest/icons/lucide';

export default component$(() => {
  useStyles$(styles);
  const users = ['Tim', 'Ryan', 'Jim', 'Jessie', 'Abby'];
  const display = useSignal<string[]>([]);
  const selected = useSignal<string[]>([]);

  return (
    <Select.Root
      multiple
      bind:displayValue={display}
      bind:value={selected}
      class="select"
    >
      <Select.Label>Logged in users</Select.Label>
      <Select.Trigger class="select-trigger">
        <Select.DisplayValue>
          {display.value.map((item) => (
            <span class="select-pill" key={item}>
              {item}
              <span
                onClick$={() => {
                  selected.value = selected.value?.filter(
                    (selectedItem) => selectedItem !== item,
                  );
                }}
              >
                <LuX aria-hidden="true" />
              </span>
            </span>
          ))}
        </Select.DisplayValue>
      </Select.Trigger>
      <Select.Popover class="select-popover">
        {users.map((user) => (
          <Select.Item class="select-item" key={user}>
            <Select.ItemLabel>{user}</Select.ItemLabel>
            <Select.ItemIndicator>
              <LuCheck />
            </Select.ItemIndicator>
          </Select.Item>
        ))}
      </Select.Popover>
    </Select.Root>
  );
});

// internal
import styles from '../snippets/select.css?inline';

The above example shows the selected values which can be filtered by clicking on the cancel icon.

Typeahead

The select offers a typeahead feature that allows users to quickly find items by typing.

Logged in users

import { component$, useStyles$ } from '@builder.io/qwik';
import { Select } from '@qwik-ui/headless';
import styles from '../snippets/select.css?inline';

export default component$(() => {
  useStyles$(styles);
  const users = ['Tim', 'Ryan', 'Jim', 'Jessie', 'Abby'];

  return (
    <Select.Root class="select">
      <Select.Label>Logged in users</Select.Label>
      <Select.Trigger class="select-trigger">
        <Select.DisplayValue placeholder="Select an option" />
      </Select.Trigger>
      <Select.Popover class="select-popover">
        {users.map((user) => (
          <Select.Item key={user}>
            <Select.ItemLabel>{user}</Select.ItemLabel>
          </Select.Item>
        ))}
      </Select.Popover>
    </Select.Root>
  );
});

It reduces the need to scroll through the available items. Typeahead is particularly handy for expected data sets, such as a list of countries.

Handling listbox open / close

We may want to handle the open / close of the listbox. For example, we may want to show a loading indicator when the listbox is open.

It is currently: closed

Logged in users

The listbox opened and closed 0 time(s)

import { $, component$, useSignal, useStyles$ } from '@builder.io/qwik';
import { Select } from '@qwik-ui/headless';

export default component$(() => {
  useStyles$(styles);
  const users = ['Tim', 'Ryan', 'Jim', 'Jessie', 'Abby'];
  const changeCount = useSignal(0);
  const isOpen = useSignal(false);

  const handleOpenChange$ = $((open: boolean): void => {
    isOpen.value = open;
    changeCount.value++;
  });

  return (
    <>
      <span>It is currently: {isOpen.value ? 'open' : 'closed'}</span>
      <Select.Root onOpenChange$={handleOpenChange$} class="select">
        <Select.Label>Logged in users</Select.Label>
        <Select.Trigger class="select-trigger">
          <Select.DisplayValue placeholder="Select an option" />
        </Select.Trigger>
        <Select.Popover class="select-popover">
          {users.map((user) => (
            <Select.Item key={user}>
              <Select.ItemLabel>{user}</Select.ItemLabel>
            </Select.Item>
          ))}
        </Select.Popover>
      </Select.Root>
      <p>The listbox opened and closed {changeCount.value} time(s)</p>
    </>
  );
});

// internal
import styles from '../snippets/select.css?inline';

To do that, we can use the onOpenChange$ prop. A parameter is passed to the handler, which is a boolean indicating whether the listbox is open or closed.

Looping

To loop through the items, we can use the loop boolean prop on the <Select.Root /> component.

Logged in users

import { component$, useStyles$ } from '@builder.io/qwik';
import { Select } from '@qwik-ui/headless';

export default component$(() => {
  useStyles$(styles);
  const users = ['Tim', 'Ryan', 'Jim', 'Jessie', 'Abby'];

  return (
    <Select.Root loop={true} class="select">
      <Select.Label>Logged in users</Select.Label>
      <Select.Trigger class="select-trigger">
        <Select.DisplayValue placeholder="Select an option" />
      </Select.Trigger>
      <Select.Popover class="select-popover">
        {users.map((user) => (
          <Select.Item key={user}>
            <Select.ItemLabel>{user}</Select.ItemLabel>
          </Select.Item>
        ))}
      </Select.Popover>
    </Select.Root>
  );
});

// internal
import styles from '../snippets/select.css?inline';

Pressing the down arrow key will move focus to the first item in the list.
Pressing the up arrow key will move focus to the last item in the list.

Grouped items

import { component$, useStyles$ } from '@builder.io/qwik';
import { Select } from '@qwik-ui/headless';

export default component$(() => {
  useStyles$(styles);
  const users = ['Tim', 'Ryan', 'Jim', 'Abby'];
  const animals = ['Dog', 'Cat', 'Bird'];

  return (
    <Select.Root class="select">
      <Select.Trigger class="select-trigger">
        <Select.DisplayValue placeholder="Select an option" />
      </Select.Trigger>
      <Select.Popover class="select-popover">
        <Select.Group>
          <Select.GroupLabel class="select-label">People</Select.GroupLabel>
          {users.map((user) => (
            <Select.Item key={user}>
              <Select.ItemLabel>{user}</Select.ItemLabel>
            </Select.Item>
          ))}
        </Select.Group>
        <Select.Group>
          <Select.GroupLabel class="select-group-label">Animals</Select.GroupLabel>
          {animals.map((animal) => (
            <Select.Item key={animal}>
              <Select.ItemLabel>{animal}</Select.ItemLabel>
            </Select.Item>
          ))}
        </Select.Group>
      </Select.Popover>
    </Select.Root>
  );
});

// internal
import styles from '../snippets/select.css?inline';

The <Select.Group /> and <Select.GroupLabel /> components are used to group and provide an accessible name to the Grouped items.

Wrap the items in a group, add a Label, and you're good to go!

Scrolling

Because focus remains on the select trigger when the listbox is open, it's important to handle scrolling in the listbox.

import { component$, useStyles$ } from '@builder.io/qwik';
import { Select } from '@qwik-ui/headless';

export default component$(() => {
  useStyles$(styles);
  const users = ['Tim', 'Ryan', 'Jim', 'Jessie', 'Abby'];
  const animals = ['Dog', 'Cat', 'Bird', 'Fish', 'Snake'];

  return (
    <Select.Root class="select">
      <Select.Trigger class="select-trigger">
        <Select.DisplayValue placeholder="Select an option" />
      </Select.Trigger>
      <Select.Popover class="select-popover select-max-height">
        <Select.Group>
          <Select.GroupLabel class="select-label">People</Select.GroupLabel>
          {users.map((user) => (
            <Select.Item key={user}>
              <Select.ItemLabel>{user}</Select.ItemLabel>
            </Select.Item>
          ))}
        </Select.Group>
        <Select.Group>
          <Select.GroupLabel class="select-label">Animals</Select.GroupLabel>
          {animals.map((animal) => (
            <Select.Item key={animal}>
              <Select.ItemLabel>{animal}</Select.ItemLabel>
            </Select.Item>
          ))}
        </Select.Group>
      </Select.Popover>
    </Select.Root>
  );
});

// internal
import styles from '../snippets/select.css?inline';

The native scrollIntoView method is used to scroll the itemss into view when the user highlights an items.

To customize the scroll behavior, add the scrollOptions prop to the <Select.Root /> component.

Placeholder

We can provide a custom placeholder to the <Select.DisplayValue /> component by adding the placeholder prop.

Logged in users

import { component$, useStyles$ } from '@builder.io/qwik';
import { Select } from '@qwik-ui/headless';

export default component$(() => {
  useStyles$(styles);
  const users = ['Tim', 'Ryan', 'Jim', 'Jessie', 'Abby'];

  return (
    <Select.Root class="select">
      <Select.Label>Logged in users</Select.Label>
      <Select.Trigger class="select-trigger">
        <Select.DisplayValue placeholder="Select an option" />
      </Select.Trigger>
      <Select.Popover class="select-popover">
        {users.map((user) => (
          <Select.Item class="select-item" key={user}>
            <Select.ItemLabel>{user}</Select.ItemLabel>
            <Select.ItemIndicator>
              <LuCheck />
            </Select.ItemIndicator>
          </Select.Item>
        ))}
      </Select.Popover>
    </Select.Root>
  );
});

// internal
import styles from '../snippets/select.css?inline';
import { LuCheck } from '@qwikest/icons/lucide';

When a value is not selected, the placeholder is displayed.

CSR

The select component can be rendered both server-side or client-side, same with the rest of the components.

import { component$, useSignal, useStyles$ } from '@builder.io/qwik';
import { Select } from '@qwik-ui/headless';

export default component$(() => {
  useStyles$(styles);
  const users = ['Tim', 'Ryan', 'Jim', 'Jessie', 'Abby'];
  const renderSelect = useSignal(false);

  return (
    <>
      <button onClick$={() => (renderSelect.value = true)}>CSR mode</button>
      {renderSelect.value && (
        <Select.Root class="select">
          <Select.Label>Logged in users</Select.Label>
          <Select.Trigger class="select-trigger">
            <Select.DisplayValue placeholder="Select an option" />
          </Select.Trigger>
          <Select.Popover class="select-popover">
            {users.map((user) => (
              <Select.Item key={user}>
                <Select.ItemLabel>{user}</Select.ItemLabel>
              </Select.Item>
            ))}
          </Select.Popover>
        </Select.Root>
      )}
    </>
  );
});

// internal
import styles from '../snippets/select.css?inline';
