API#

useSelect<T>(
  props: AriaSelectOptions<T>,
  state: SelectState<T>,
  ref: RefObject<FocusableElement>
): SelectAria<T>

Features#

A select can be built using the <select> and <option> HTML elements, but this is not possible to style consistently cross browser, especially the options. useSelect helps achieve accessible select components that can be styled as needed without compromising on high quality interactions.

Exposed to assistive technology as a button with a listbox popup using ARIA (combined with useListBox)
Support for selecting a single option
Support for disabled options
Support for sections
Labeling support for accessibility
Support for description and error message help text linked to the input via ARIA
Support for mouse, touch, and keyboard interactions
Tab stop focus management
Keyboard support for opening the listbox using the arrow keys, including automatically focusing the first or last item accordingly
Typeahead to allow selecting options by typing text, even without opening the listbox
Browser autofill integration via a hidden native <select> element
Support for mobile form navigation via software keyboard
Mobile screen reader listbox dismissal support

Anatomy#

A select consists of a label, a button which displays a selected value, and a listbox, displayed in a popup. Users can click, touch, or use the keyboard on the button to open the listbox popup. useSelect handles exposing the correct ARIA attributes for accessibility and handles the interactions for the select in its collapsed state. It should be combined with useListBox, which handles the implementation of the popup listbox.

useSelect also supports optional description and error message elements, which can be used to provide more context about the field, and any validation messages. These are linked with the input via the aria-describedby attribute.

useSelect returns props that you should spread onto the appropriate element:

Name	Type	Description
`labelProps`	`DOMAttributes`	Props for the label element.
`triggerProps`	`AriaButtonProps`	Props for the popup trigger element.
`valueProps`	`DOMAttributes`	Props for the element representing the selected value.
`menuProps`	`AriaListBoxOptions<T>`	Props for the popup.
`descriptionProps`	`DOMAttributes`	Props for the select's description element, if any.
`errorMessageProps`	`DOMAttributes`	Props for the select's error message element, if any.

State is managed by the useSelectState hook from @react-stately/select. The state object should be passed as an option to useSelect

If a select does not have a visible label, an aria-label or aria-labelledby prop must be passed instead to identify it to assistive technology.

State management#

useSelect requires knowledge of the options in the select in order to handle keyboard navigation and other interactions. It does this using the Collection interface, which is a generic interface to access sequential unique keyed data. You can implement this interface yourself, e.g. by using a prop to pass a list of item objects, but useSelectState from @react-stately/select implements a JSX based interface for building collections instead. See Collection Components for more information, and Collection Interface for internal details.

In addition, useSelectState manages the state necessary for multiple selection and exposes a SelectionManager, which makes use of the collection to provide an interface to update the selection state. It also holds state to track if the popup is open. For more information about selection, see Selection.

Example#

This example uses a <button> element for the trigger, with a <span> inside to hold the value, and another for the dropdown arrow icon (hidden from screen readers with aria-hidden). A <HiddenSelect> is used to render a hidden native <select>, which enables browser form autofill support.

The same Popover, ListBox, and Button components created with usePopover, useListBox, and useButton that you may already have in your component library or application should be reused. These can be shared with other components such as a ComboBox created with useComboBox or a Dialog popover created with useDialog. The code for these components is also included below in the collapsed sections.

In addition, see useListBox for examples of sections (option groups), and more complex options. For an example of the description and error message elements, see useTextField.

Button#

The Button component is used in the above example to toggle the listbox popup. It is built using the useButton hook, and can be shared with many other components.

Show code

import {useButton} from 'react-aria';

function Button(props) {
  let ref = props.buttonRef;
  let { buttonProps } = useButton(props, ref);
  return (
    <button {...buttonProps} ref={ref} style={props.style}>
      {props.children}
    </button>
  );
}

import {useButton} from 'react-aria';

function Button(props) {
  let ref = props.buttonRef;
  let { buttonProps } = useButton(props, ref);
  return (
    <button {...buttonProps} ref={ref} style={props.style}>
      {props.children}
    </button>
  );
}

import {useButton} from 'react-aria';

function Button(props) {
  let ref =
    props.buttonRef;
  let { buttonProps } =
    useButton(
      props,
      ref
    );
  return (
    <button
      {...buttonProps}
      ref={ref}
      style={props.style}
    >
      {props.children}
    </button>
  );

Styled examples#

Tailwind CSS

An example of styling a Select with Tailwind.

Styled Components

A Select with complex item content built with Styled Components.

Popup positioning

A Select with custom macOS-style popup positioning.

Usage#

The following examples show how to use the Select component created in the above example.

Dynamic collections#

Select follows the Collection Components API, accepting both static and dynamic collections. The examples above show static collections, which 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.

As seen below, an iterable list of options is passed to the Select using the items prop. Each item accepts a key prop, which is passed to the onSelectionChange handler 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.

function Example() {
  let options = [
    {id: 1, name: 'Aerospace'},
    {id: 2, name: 'Mechanical'},
    {id: 3, name: 'Civil'},
    {id: 4, name: 'Biomedical'},
    {id: 5, name: 'Nuclear'},
    {id: 6, name: 'Industrial'},

Controlled selection#

Setting a selected option can be done by using the defaultSelectedKey or selectedKey prop. The selected key corresponds to the key of an item. When Select is used with a dynamic collection as described above, the key of each item is derived from the data. See the react-stately Selection docs for more details.

function Example() {
  let options = [
    {name: 'Koala'},
    {name: 'Kangaroo'},
    {name: 'Platypus'},
    {name: 'Bald Eagle'},
    {name: 'Bison'},
    {name: 'Skunk'}
  ];
  let [animal, setAnimal] = React.useState("Bison");

  return (
    <Select
      label="Pick an animal (controlled)"
      items={options}
      selectedKey={animal}
      onSelectionChange={selected => setAnimal(selected)}>
      {item => <Item key={item.name}>{item.name}</Item>}
    </Select>
  );
}

function Example() {
  let options = [
    {name: 'Koala'},
    {name: 'Kangaroo'},
    {name: 'Platypus'},
    {name: 'Bald Eagle'},
    {name: 'Bison'},
    {name: 'Skunk'}
  ];
  let [animal, setAnimal] = React.useState("Bison");

  return (
    <Select
      label="Pick an animal (controlled)"
      items={options}
      selectedKey={animal}
      onSelectionChange={selected => setAnimal(selected)}>
      {item => <Item key={item.name}>{item.name}</Item>}
    </Select>
  );
}

function Example() {
  let options = [
    { name: 'Koala' },
    { name: 'Kangaroo' },
    { name: 'Platypus' },
    {
      name: 'Bald Eagle'
    },
    { name: 'Bison' },
    { name: 'Skunk' }
  ];
  let [
    animal,
    setAnimal
  ] = React.useState(
    'Bison'
  );

  return (
    <Select
      label="Pick an animal (controlled)"
      items={options}
      selectedKey={animal}
      onSelectionChange={(selected) =>
        setAnimal(
          selected
        )}
    >
      {(item) => (
        <Item
          key={item.name}
        >
          {item.name}
        </Item>
      )}
    </Select>
  );
}

Asynchronous loading#

This example uses the useAsyncList hook to handle asynchronous loading of data from a server. You may additionally want to display a spinner to indicate the loading state to the user, or support features like infinite scroll to load more data.

import {useAsyncList} from 'react-stately';

function AsyncLoadingExample() {
  let list = useAsyncList({
    async load({ signal, filterText }) {
      let res = await fetch(
        `https://pokeapi.co/api/v2/pokemon`,
        { signal }
      );
      let json = await res.json();

      return {
        items: json.results
      };
    }
  });

  return (
    <Select label="Pick a Pokemon" items={list.items} selectionMode="single">
      {(item) => (
        <Item key={item.name}>
          {item.name}
        </Item>
      )}
    </Select>
  );
}

import {useAsyncList} from 'react-stately';

function AsyncLoadingExample() {
  let list = useAsyncList({
    async load({ signal, filterText }) {
      let res = await fetch(
        `https://pokeapi.co/api/v2/pokemon`,
        { signal }
      );
      let json = await res.json();

      return {
        items: json.results
      };
    }
  });

  return (
    <Select
      label="Pick a Pokemon"
      items={list.items}
      selectionMode="single"
    >
      {(item) => <Item key={item.name}>{item.name}</Item>}
    </Select>
  );
}

import {useAsyncList} from 'react-stately';

function AsyncLoadingExample() {
  let list =
    useAsyncList({
      async load(
        {
          signal,
          filterText
        }
      ) {
        let res =
          await fetch(
            `https://pokeapi.co/api/v2/pokemon`,
            { signal }
          );
        let json =
          await res
            .json();

        return {
          items:
            json.results
        };
      }
    });

  return (
    <Select
      label="Pick a Pokemon"
      items={list.items}
      selectionMode="single"
    >
      {(item) => (
        <Item
          key={item.name}
        >
          {item.name}
        </Item>
      )}
    </Select>
  );
}

Disabled#

A Select can be fully disabled using the isDisabled prop.

<Select label="Choose frequency" isDisabled>
  <Item key="rarely">Rarely</Item>
  <Item key="sometimes">Sometimes</Item>
  <Item key="always">Always</Item>
</Select>

<Select label="Choose frequency" isDisabled>
  <Item key="rarely">Rarely</Item>
  <Item key="sometimes">Sometimes</Item>
  <Item key="always">Always</Item>
</Select>

<Select
  label="Choose frequency"
  isDisabled
>
  <Item key="rarely">
    Rarely
  </Item>
  <Item key="sometimes">
    Sometimes
  </Item>
  <Item key="always">
    Always
  </Item>
</Select>

Disabled options#

useSelect supports marking items as disabled using the disabledKeys prop. Each key in this list corresponds with the key prop passed to the Item component, or automatically derived from the values passed to the items prop. See Collections for more details.

Disabled items are not focusable, selectable, or keyboard navigable. The isDisabled property returned by useOption can be used to style the item appropriately.

<Select label="Favorite Animal" disabledKeys={['cat', 'kangaroo']}>
  <Item key="red panda">Red Panda</Item>
  <Item key="cat">Cat</Item>
  <Item key="dog">Dog</Item>
  <Item key="aardvark">Aardvark</Item>
  <Item key="kangaroo">Kangaroo</Item>
  <Item key="snake">Snake</Item>
</Select>

<Select
  label="Favorite Animal"
  disabledKeys={['cat', 'kangaroo']}
>
  <Item key="red panda">Red Panda</Item>
  <Item key="cat">Cat</Item>
  <Item key="dog">Dog</Item>
  <Item key="aardvark">Aardvark</Item>
  <Item key="kangaroo">Kangaroo</Item>
  <Item key="snake">Snake</Item>
</Select>

<Select
  label="Favorite Animal"
  disabledKeys={[
    'cat',
    'kangaroo'
  ]}
>
  <Item key="red panda">
    Red Panda
  </Item>
  <Item key="cat">
    Cat
  </Item>
  <Item key="dog">
    Dog
  </Item>
  <Item key="aardvark">
    Aardvark
  </Item>
  <Item key="kangaroo">
    Kangaroo
  </Item>
  <Item key="snake">
    Snake
  </Item>
</Select>

Controlled open state#

The open state of the select can be controlled via the defaultOpen and isOpen props

function Example() {
  let [open, setOpen] = React.useState(false);

  return (
    <>
      <p>Select is {open ? 'open' : 'closed'}</p>
      <Select label="Choose frequency" isOpen={open} onOpenChange={setOpen}>
        <Item key="rarely">Rarely</Item>
        <Item key="sometimes">Sometimes</Item>
        <Item key="always">Always</Item>
      </Select>
    </>
  );
}

function Example() {
  let [open, setOpen] = React.useState(false);

  return (
    <>
      <p>Select is {open ? 'open' : 'closed'}</p>
      <Select
        label="Choose frequency"
        isOpen={open}
        onOpenChange={setOpen}
      >
        <Item key="rarely">Rarely</Item>
        <Item key="sometimes">Sometimes</Item>
        <Item key="always">Always</Item>
      </Select>
    </>
  );
}

function Example() {
  let [open, setOpen] =
    React.useState(
      false
    );

  return (
    <>
      <p>
        Select is {open
          ? 'open'
          : 'closed'}
      </p>
      <Select
        label="Choose frequency"
        isOpen={open}
        onOpenChange={setOpen}
      >
        <Item key="rarely">
          Rarely
        </Item>
        <Item key="sometimes">
          Sometimes
        </Item>
        <Item key="always">
          Always
        </Item>
      </Select>
    </>
  );
}

Internationalization#

useSelect and useListBox handle some aspects of internationalization automatically. For example, type to select is implemented with an Intl.Collator for internationalized string matching. You are responsible for localizing all labels and option content that is passed into the select.

RTL#

In right-to-left languages, the select should be mirrored. The arrow should be on the left, and the selected value should be on the right. In addition, the content of list options should flip. Ensure that your CSS accounts for this.
