Content#

A ListBox displays a list of options, and allows users to select one or more of them. It follows the Collection Components API, accepting both static and dynamic collections. Similar to Picker, ListBox accepts <Item> elements as children, each with a key prop. Basic usage of the ListBox, seen in the example above, shows multiple options populated with a string. Static collections, as in this example, can be used when the full list of options is known ahead of time.

Dynamic collections, as shown below, can be used when the options come from an external data source such as an API call, or update over time. Providing the data in this way allows for ListBox to automatically cache the rendering of each item, which dramatically improves performance.

As seen below, an iterable list of options is passed to the Listbox using the items prop. Each item accepts a key prop, which is passed to the onSelectionChange handler, when present, to identify the selected item. Alternatively, if the item objects contain an id property, as shown in the example below, then this is used automatically and a key prop is not required. See the Events section for more detail on selection. By default, selection is not enabled, however this can be changed using the selectionMode prop. See Selection for more information.

function Example() {
  let options = [
    { id: 1, name: 'Aardvark' },
    { id: 2, name: 'Cat' },
    { id: 3, name: 'Dog' },
    { id: 4, name: 'Kangaroo' },
    { id: 5, name: 'Koala' },
    { id: 6, name: 'Penguin' },

Accessibility#

ListBoxes should be labeled using the aria-label prop. If the ListBox is labeled by a separate element, an aria-labelledby prop must be provided using the id of the labeling element instead.

Internationalization#

To internationalize a ListBox, a localized string should be passed to the children of each Item. For languages that are read right to left (e.g. Hebrew and Arabic), the layout of the ListBox is flipped.

Selection#

ListBox supports no selection, single and multiple selection modes using the selectionMode prop. Setting selected options can be done by using the defaultSelectedKeys or selectedKeys prop. The selected key corresponds to the key of an item. See Events for more details on selection events. Additionally, see the react-stately Selection docs for caveats regarding selection prop typing.

Links#

By default, interacting with an item in a ListBox triggers onSelectionChange. Alternatively, items may be links to another page or website. This can be achieved by passing the href prop to the <Item> component. Link items in a ListBox are not selectable.

<ListBox aria-label="Links">
  <Item href="https://adobe.com/" target="_blank">Adobe</Item>
  <Item href="https://apple.com/" target="_blank">Apple</Item>
  <Item href="https://google.com/" target="_blank">Google</Item>
  <Item href="https://microsoft.com/" target="_blank">Microsoft</Item>
</ListBox>

<ListBox aria-label="Links">
  <Item href="https://adobe.com/" target="_blank">
    Adobe
  </Item>
  <Item href="https://apple.com/" target="_blank">
    Apple
  </Item>
  <Item href="https://google.com/" target="_blank">
    Google
  </Item>
  <Item href="https://microsoft.com/" target="_blank">
    Microsoft
  </Item>
</ListBox>

<ListBox aria-label="Links">
  <Item
    href="https://adobe.com/"
    target="_blank"
  >
    Adobe
  </Item>
  <Item
    href="https://apple.com/"
    target="_blank"
  >
    Apple
  </Item>
  <Item
    href="https://google.com/"
    target="_blank"
  >
    Google
  </Item>
  <Item
    href="https://microsoft.com/"
    target="_blank"
  >
    Microsoft
  </Item>
</ListBox>

Client side routing#

The <Item> component works with frameworks and client side routers like Next.js and React Router. As with other React Spectrum components that support links, this works via the Provider component at the root of your app. See the client side routing guide to learn how to set this up.

Sections#

ListBox supports sections in order to group options. Sections can be used by wrapping groups of Items in a Section component. Each Section takes a title and key prop.

Static Items#

<ListBox
  width="size-2400"
  aria-label="Pick your favorite"
  selectionMode="single"
>
  <Section title="Animals">
    <Item key="Aardvark">Aardvark</Item>
    <Item key="Kangaroo">Kangaroo</Item>
    <Item key="Snake">Snake</Item>
  </Section>
  <Section title="People">
    <Item key="Danni">Danni</Item>
    <Item key="Devon">Devon</Item>
    <Item key="Ross">Ross</Item>
  </Section>
</ListBox>

<ListBox
  width="size-2400"
  aria-label="Pick your favorite"
  selectionMode="single"
>
  <Section title="Animals">
    <Item key="Aardvark">Aardvark</Item>
    <Item key="Kangaroo">Kangaroo</Item>
    <Item key="Snake">Snake</Item>
  </Section>
  <Section title="People">
    <Item key="Danni">Danni</Item>
    <Item key="Devon">Devon</Item>
    <Item key="Ross">Ross</Item>
  </Section>
</ListBox>

<ListBox
  width="size-2400"
  aria-label="Pick your favorite"
  selectionMode="single"
>
  <Section title="Animals">
    <Item key="Aardvark">
      Aardvark
    </Item>
    <Item key="Kangaroo">
      Kangaroo
    </Item>
    <Item key="Snake">
      Snake
    </Item>
  </Section>
  <Section title="People">
    <Item key="Danni">
      Danni
    </Item>
    <Item key="Devon">
      Devon
    </Item>
    <Item key="Ross">
      Ross
    </Item>
  </Section>
</ListBox>

Dynamic Items#

Sections used with dynamic items are populated from a hierarchical data structure. Similarly to the props on ListBox, Section takes an array of data using the items prop.

import type {Selection} from '@adobe/react-spectrum';

function Example() {
  let options = [
    {name: 'Australian', children: [
      {id: 2, name: 'Koala'},
      {id: 3, name: 'Kangaroo'},
      {id: 4, name: 'Platypus'}
    ]},
    {name: 'American', children: [
      {id: 6, name: 'Bald Eagle'},
      {id: 7, name: 'Bison'},
      {id: 8, name: 'Skunk'}
    ]}
  ];
  let [selected, setSelected] = React.useState<Selection>(new Set());

  return (
    <ListBox
      aria-label="Pick an animal"

      width="size-2400">
      {item => (
        <Section key={item.name} items={item.children} title={item.name}>
          {item => <Item>{item.name}</Item>}
        </Section>
      )}
    </ListBox>
  );
}

import type {Selection} from '@adobe/react-spectrum';

          title={item.name}
        >
          {(item) => <Item>{item.name}</Item>}
        </Section>
      )}
    </ListBox>
  );
}

        </Section>
      )}
    </ListBox>
  );
}

Events#

ListBox supports selection via mouse, keyboard, and touch. You can handle all of these via the onSelectionChange prop. ListBox will pass the selected key to the onSelectionChange handler.

The following example uses an onSelectionChange handler to update the selection stored in React state.

import type {Selection} from '@adobe/react-spectrum';

function StaticExample() {
  let [frequency, setFrequency] = React.useState<Selection>(new Set());

  return (
    <>
      <ListBox
        aria-label="Choose frequency"
        selectionMode="single"
        onSelectionChange={selected => setFrequency(selected)}
        width="size-2400">
        <Item key="Rarely">Rarely</Item>
        <Item key="Sometimes">Sometimes</Item>
        <Item key="Always">Always</Item>
      </ListBox>
      <p>You selected: {[...frequency][0]}</p>
    </>
  );
}

import type {Selection} from '@adobe/react-spectrum';

function StaticExample() {
  let [frequency, setFrequency] = React.useState<Selection>(
    new Set()
  );

  return (
    <>
      <ListBox
        aria-label="Choose frequency"
        selectionMode="single"
        onSelectionChange={(selected) =>
          setFrequency(selected)}
        width="size-2400"
      >
        <Item key="Rarely">Rarely</Item>
        <Item key="Sometimes">Sometimes</Item>
        <Item key="Always">Always</Item>
      </ListBox>
      <p>You selected: {[...frequency][0]}</p>
    </>
  );
}

import type {Selection} from '@adobe/react-spectrum';

function StaticExample() {
  let [
    frequency,
    setFrequency
  ] = React.useState<
    Selection
  >(new Set());

  return (
    <>
      <ListBox
        aria-label="Choose frequency"
        selectionMode="single"
        onSelectionChange={(selected) =>
          setFrequency(
            selected
          )}
        width="size-2400"
      >
        <Item key="Rarely">
          Rarely
        </Item>
        <Item key="Sometimes">
          Sometimes
        </Item>
        <Item key="Always">
          Always
        </Item>
      </ListBox>
      <p>
        You selected:
        {' '}
        {[...frequency][
          0
        ]}
      </p>
    </>
  );
}

When using ListBox with dynamic items, selection works much the same way using key. However, if your data already has an id property (as is common with many data sets), ListBox can use that id without needing to specify a key prop. The below example shows ListBox using the id of each item from the items array as the selected value without the need for key. Note that key will always take precedence if set.

import type {Selection} from '@adobe/react-spectrum';

function DynamicExample() {
  let [animalId, setAnimalId] = React.useState<Selection>(new Set());
  let options = [
    {id: 1, name: 'Aardvark'},
    {id: 2, name: 'Cat'},
    {id: 3, name: 'Dog'},
    {id: 4, name: 'Kangaroo'},
    {id: 5, name: 'Koala'},
    {id: 6, name: 'Penguin'},
    {id: 7, name: 'Snake'},
    {id: 8, name: 'Turtle'},
    {id: 9, name: 'Wombat'}
  ];

  return (
    <>
      <ListBox
        selectionMode="single"
        aria-label="Pick an animal"
        items={options}
        onSelectionChange={selected => setAnimalId(selected)}
        width="size-2400">
        {item => <Item>{item.name}</Item>}
      </ListBox>
      <p>Your favorite animal has id: {[...animalId][0]}</p>
    </>
  );
}

import type {Selection} from '@adobe/react-spectrum';

function DynamicExample() {
  let [animalId, setAnimalId] = React.useState<Selection>(
    new Set()

Complex Items#

Items within ListBox also allow for additional content used to better communicate options. Icons, avatars, and descriptions can be added to the children of Item as shown in the example below. If a description is added, the prop slot="description" must be used to distinguish the different <Text> elements. See Icon's labeling section and Avatar's accessibility section for more information on how to label these elements.

<ListBox width="size-2400" aria-label="Options" selectionMode="single">

Asynchronous loading#

ListBox supports loading data asynchronously, and will display a progress circle when the isLoading prop is set. It also supports infinite scrolling to load more data on demand as the user scrolls, via the onLoadMore prop.

This example uses the useAsyncList hook to handle loading the data. See the docs for more information.

import {useAsyncList} from 'react-stately';

interface Pokemon {
  name: string;
}

function AsyncLoadingExample() {
  let list = useAsyncList<Pokemon>({
    async load({ signal, cursor }) {
      // If no cursor is available, then we're loading the first page.
      // Otherwise, the cursor is the next URL to load, as returned from the previous page.
      let res = await fetch(cursor || 'https://pokeapi.co/api/v2/pokemon', {
        signal
      });
      let json = await res.json();
      return {
        items: json.results,
        cursor: json.next
      };
    }
  });

  return (
    <Flex maxHeight="size-2400">
      <ListBox
        aria-label="Pick a Pokemon"

        onLoadMore={list.loadMore}
        width="size-2400"
      >
        {(item) => <Item key={item.name}>{item.name}</Item>}
      </ListBox>
    </Flex>

Testing#

The ListBox features automatic virtualization and may need specific mocks in a test environment to enable said virtualization properly. Please see the following sections in the testing docs for more information on how to handle these behaviors in your test suite.

Timers

Virtualized Components

Please also refer to React Spectrum's test suite if you find that the above isn't sufficient when resolving issues in your own test cases.

Test utils alpha#

@react-spectrum/test-utils offers common listbox interaction utilities which you may find helpful when writing tests. See here for more information on how to setup these utilities in your tests. Below is the full definition of the listbox tester and a sample of how you could use it in your test suite.

// ListBox.test.ts
import {render} from '@testing-library/react';
import {theme} from '@react-spectrum/theme-default';
import {User} from '@react-spectrum/test-utils';

let testUtilUser = new User({ interactionType: 'mouse' });
// ...

it('ListBox can select an option via keyboard', async function () {
  // Render your test component/app and initialize the listbox tester
  let { getByTestId } = render(
    <Provider theme={defaultTheme}>
      <ListBox selectionMode="single" data-testid="test-listbox">
        ...
      </ListBox>
    </Provider>
  );
  let listboxTester = testUtilUser.createTester('ListBox', {
    root: getByTestId('test-listbox'),
    interactionType: 'keyboard'
  });

  await listboxTester.toggleOptionSelection({ option: 4 });
  expect(listboxTester.options()[4]).toHaveAttribute('aria-selected', 'true');
});
