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. Select helps achieve accessible select components that can be styled as needed without compromising on high quality interactions.

Flexible – Support for controlled and uncontrolled state, async loading, disabled items, validation, sections, complex items, and more.
Keyboard navigation – Select can be opened and navigated using the arrow keys, along with page up/down, home/end, etc. Auto scrolling, and typeahead both in the listbox and on the button, are supported as well.
Accessible – Follows the ARIA listbox pattern, with support for items and sections, and slots for label and description elements within each item for improved screen reader announcement.
HTML form integration – A visually hidden <select> element is included to enable HTML form integration, autofill, and mobile form navigation via the software keyboard.
Styleable – Items include builtin states for styling, such as hover, press, focus, selected, and disabled.

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.

Select 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.

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.

Concepts#

Select makes use of the following concepts:

Composed components#

A Select uses the following components, which may also be used standalone or reused in other components.

Label

A label provides context for an input element.

Button

A button allows a user to perform an action.

Popover

A popover displays content in context with a trigger element.

ListBox

A listbox allows a user to select one or more options from a list.

Styling#

React Aria components can be styled in many ways, including using CSS classes, inline styles, utility classes (e.g. Tailwind), CSS-in-JS (e.g. Styled Components), etc. By default, all components include a builtin className attribute which can be targeted using CSS selectors. These follow the react-aria-ComponentName naming convention.

.react-aria-Select {
  /* ... */
}

.react-aria-Select {
  /* ... */
}

.react-aria-Select {
  /* ... */
}

A custom className can also be specified on any component. This overrides the default className provided by React Aria with your own.

<Select className="my-select">
  {/* ... */}
</Select>

<Select className="my-select">
  {/* ... */}
</Select>

<Select className="my-select">
  {/* ... */}
</Select>

In addition, some components support multiple UI states (e.g. pressed, hovered, etc.). React Aria components expose states using DOM attributes, which you can target in CSS selectors. These are ARIA attributes wherever possible, or data attributes when a relevant ARIA attribute does not exist. For example:

.react-aria-Item[aria-selected=true] {
  /* ... */
}

.react-aria-Item[data-focused] {
  /* ... */
}

.react-aria-Item[aria-selected=true] {
  /* ... */
}

.react-aria-Item[data-focused] {
  /* ... */
}

.react-aria-Item[aria-selected=true] {
  /* ... */
}

.react-aria-Item[data-focused] {
  /* ... */
}

The className and style props also accept functions which receive states for styling. This lets you dynamically determine the classes or styles to apply, which is useful when using utility CSS libraries like Tailwind.

<Item
  className={({ isSelected }) => isSelected ? 'bg-blue-400' : 'bg-gray-100'}
>
  Item
</Item>

<Item
  className={({ isSelected }) =>
    isSelected ? 'bg-blue-400' : 'bg-gray-100'}
>
  Item
</Item>

<Item
  className={(
    { isSelected }
  ) =>
    isSelected
      ? 'bg-blue-400'
      : 'bg-gray-100'}
>
  Item
</Item>

Render props may also be used as children to alter what elements are rendered based on the current state. For example, you could render a checkmark icon when an item is selected.

<Item>
  {({isSelected}) => (
    <>
      {isSelected && <CheckmarkIcon />}
      Item
    </>
  )}
</Item>

<Item>
  {({isSelected}) => (
    <>
      {isSelected && <CheckmarkIcon />}
      Item
    </>
  )}
</Item>

<Item>
  {(
    { isSelected }
  ) => (
    <>
      {isSelected && (
        <CheckmarkIcon />
      )}
      Item
    </>
  )}
</Item>

The states and selectors for each component used in a Select are documented below.

Select#

A Select can be targeted with the .react-aria-Select CSS selector, or by overriding with a custom className. It provides a SelectState object to its render props, which can be used to customize the className, style, or children.

Label#

A Label can be targeted with the .react-aria-Label CSS selector, or by overriding with a custom className.

Button#

A Button can be targeted with the .react-aria-Button CSS selector, or by overriding with a custom className. It supports the following states:

Name	CSS Selector	Description
`isHovered`	`[data-hovered]`	Whether the button is currently hovered with a mouse.
`isPressed`	`[data-pressed]`	Whether the button is currently in a pressed state.
`isFocused`	`:focus`	Whether the button is focused, either via a mouse or keyboard.
`isFocusVisible`	`[data-focus-visible]`	Whether the button is keyboard focused.
`isDisabled`	`:disabled`	Whether the button is disabled.

SelectValue#

A SelectValue can be targed with the .react-aria-SelectValue CSS selector, or by overriding with a custom className. It supports the following states and render props:

Name	CSS Selector	Description
`isPlaceholder`	`[data-placeholder]`	Whether the value is a placeholder.
`selectedItem`	`—`	The object value of the currently selected item.
`selectedText`	`—`	The textValue of the currently selected item.

The Popover component can be targeted with the .react-aria-Popover CSS selector, or by overriding with a custom className. Note that it renders in a React Portal, so it will not appear as a descendant of the Select in the DOM.

The --trigger-width CSS custom property will be set on the popover, which you can use to make the popover match the width of the select button.

.react-aria-Popover {
  width: var(--button-width);
}

.react-aria-Popover {
  width: var(--button-width);
}

.react-aria-Popover {
  width: var(--button-width);
}

ListBox#

A ListBox can be targeted with the .react-aria-ListBox CSS selector, or by overriding with a custom className.

Section#

A Section can be targeted with the .react-aria-Section CSS selector, or by overriding with a custom className. See sections for examples.

Header#

A Header within a Section can be targeted with the .react-aria-Header CSS selector, or by overriding with a custom className. See sections for examples.

Item#

An Item can be targeted with the .react-aria-Item CSS selector, or by overriding with a custom className. It supports the following states and render props:

Name	CSS Selector	Description
`isHovered`	`[data-hovered]`	Whether the item is currently hovered with a mouse.
`isPressed`	`[data-pressed]`	Whether the item is currently in a pressed state.
`isSelected`	`[aria-selected=true]`	Whether the item is currently selected.
`isFocused`	`[data-focused]`	Whether the item is currently focused.
`isFocusVisible`	`[data-focus-visible]`	Whether the item is currently keyboard focused.
`isDisabled`	`[aria-disabled]`	Whether the item is non-interactive, i.e. both selection and actions are disabled and the item may not be focused. Dependent on `disabledKeys` and `disabledBehavior`.
`selectionMode`	`—`	The type of selection that is allowed in the collection.
`selectionBehavior`	`—`	The selection behavior for the collection.

Items also support two slots: a label, and a description. When provided using the <Text> element, the item will have aria-labelledby and aria-describedby attributes pointing to these slots, improving screen reader announcement. See complex items for an example.

Note that items may not contain interactive children such as buttons, as screen readers will not be able to access them.

Text#

The help text elements within a Select can be targeted with the [slot=description] and [slot=errorMessage] CSS selectors, or by adding a custom className.

Reusable wrappers#

If you will use a Select in multiple places in your app, you can wrap all of the pieces into a reusable component. This way, the DOM structure, styling code, and other logic are defined in a single place and reused everywhere to ensure consistency.

This example wraps Select and all of its children together into a single component which accepts a label prop and children, which are passed through to the right places. It also shows how to use the description and errorMessage slots to render help text (see below for details). The Item component is also wrapped to apply class names based on the current state, as described above.

import type {ItemProps, SelectProps} from 'react-aria-components';
import {Text} from 'react-aria-components';

interface MySelectProps<T extends object> extends SelectProps<T> {
  label?: string;
  description?: string;

Usage#

The following examples show how to use the MySelect 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 an id 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 an id 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'},
    {id: 7, name: 'Chemical'},
    {id: 8, name: 'Agricultural'},
    {id: 9, name: 'Electrical'}
  ];

  return (
    <>
      <MySelect label="Pick an engineering major" items={options}>
        {(item) => <Item>{item.name}</Item>}
      </MySelect>
    </>
  );
}

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' },
    { id: 7, name: 'Chemical' },
    { id: 8, name: 'Agricultural' },
    { id: 9, name: 'Electrical' }
  ];

  return (
    <>
      <MySelect
        label="Pick an engineering major"
        items={options}
      >
        {(item) => <Item>{item.name}</Item>}
      </MySelect>
    </>
  );
}

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'
    },
    {
      id: 7,
      name: 'Chemical'
    },
    {
      id: 8,
      name:
        'Agricultural'
    },
    {
      id: 9,
      name: 'Electrical'
    }
  ];

  return (
    <>
      <MySelect
        label="Pick an engineering major"
        items={options}
      >
        {(item) => (
          <Item>
            {item.name}
          </Item>
        )}
      </MySelect>
    </>
  );
}

Sections#

Select supports sections in order to group options. Sections can be used by wrapping groups of items in a Section element. A <Header> element may also be included to label the section.

Static items#

import {Section, Header} from 'react-aria-components';

    </Item>
  </Section>
</MySelect>

Dynamic items#

Sections used with dynamic items are populated from a hierarchical data structure. Similarly to the props on Select, <Section> takes an array of data using the items prop. If the section also has a header, the Collection component can be used to render the child items.

import {Collection} from 'react-aria-components';

function Example() {
  let options = [
    {name: 'Fruit', children: [
      {name: 'Apple'},
      {name: 'Banana'},
      {name: 'Orange'},
      {name: 'Honeydew'},
      {name: 'Grapes'},
      {name: 'Watermelon'},
      {name: 'Cantaloupe'},
      {name: 'Pear'}
    ]},
    {name: 'Vegetable', children: [
      {name: 'Cabbage'},
      {name: 'Broccoli'},
      {name: 'Carrots'},
      {name: 'Lettuce'},
      {name: 'Spinach'},
      {name: 'Bok Choy'},
      {name: 'Cauliflower'},
      {name: 'Potatoes'}
    ]}
  ];

  return (
    <MySelect label="Preferred fruit or vegetable" items={options}>
      {section => (
        <Section id={section.name}>
          <Header>{section.name}</Header>
          <Collection items={section.children}>
            {item => <Item id={item.name}>{item.name}</Item>}
          </Collection>
        </Section>
      )}
    </MySelect>
  );
}

import {Collection} from 'react-aria-components';

function Example() {
  let options = [
    {
      name: 'Fruit',
      children: [
        { name: 'Apple' },
        { name: 'Banana' },
        { name: 'Orange' },
        { name: 'Honeydew' },
        { name: 'Grapes' },
        { name: 'Watermelon' },
        { name: 'Cantaloupe' },
        { name: 'Pear' }
      ]
    },
    {
      name: 'Vegetable',
      children: [
        { name: 'Cabbage' },
        { name: 'Broccoli' },
        { name: 'Carrots' },

        { name: 'Cauliflower' },
        { name: 'Potatoes' }
      ]
    }
  ];

  return (
    <MySelect
      label="Preferred fruit or vegetable"
      items={options}
    >
      {(section) => (
        <Section id={section.name}>
          <Header>{section.name}</Header>
          <Collection items={section.children}>
            {(item) => (
              <Item id={item.name}>{item.name}</Item>
            )}
          </Collection>
        </Section>
      )}
    </MySelect>
  );
}

import {Collection} from 'react-aria-components';

function Example() {
  let options = [
    {
      name: 'Fruit',
      children: [
        {

        },
        {

        },
        {
          name:
            'Watermelon'
        },
        {
          name:
            'Cantaloupe'
        },
        { name: 'Pear' }
      ]
    },
    {
      name: 'Vegetable',
      children: [
        {

        },
        {
          name:

        },
        {
          name: 'Carrots'
        },
        {
          name: 'Lettuce'
        },
        {
          name: 'Spinach'
        },
        {
          name:
            'Bok Choy'
        },
        {
          name:
            'Cauliflower'
        },
        {
          name:
            'Potatoes'
        }
      ]
    }
  ];

  return (
    <MySelect
      label="Preferred fruit or vegetable"
      items={options}
    >
      {(section) => (
        <Section
          id={section
            .name}
        >
          <Header>
            {section
              .name}
          </Header>
          <Collection
            items={section
              .children}
          >
            {(item) => (
              <Item
                id={item
                  .name}
              >
                {item
                  .name}
              </Item>
            )}
          </Collection>
        </Section>
      )}
    </MySelect>
  );
}

Complex items#

Items within Select also allow for additional content used to better communicate options. Icons 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.

import {Text} from 'react-aria-components';

<MySelect label="Permissions">
  <Item textValue="Read">
    <Text slot="label">Read</Text>
    <Text slot="description">Read only</Text>
  </Item>
  <Item textValue="Write">
    <Text slot="label">Write</Text>
    <Text slot="description">Read and write only</Text>
  </Item>
  <Item textValue="Admin">
    <Text slot="label">Admin</Text>
    <Text slot="description">Full access</Text>
  </Item>
</MySelect>

import {Text} from 'react-aria-components';

<MySelect label="Permissions">
  <Item textValue="Read">
    <Text slot="label">Read</Text>
    <Text slot="description">Read only</Text>
  </Item>
  <Item textValue="Write">
    <Text slot="label">Write</Text>
    <Text slot="description">Read and write only</Text>
  </Item>
  <Item textValue="Admin">
    <Text slot="label">Admin</Text>
    <Text slot="description">Full access</Text>
  </Item>
</MySelect>

import {Text} from 'react-aria-components';

<MySelect label="Permissions">
  <Item textValue="Read">
    <Text slot="label">
      Read
    </Text>
    <Text slot="description">
      Read only
    </Text>
  </Item>
  <Item textValue="Write">
    <Text slot="label">
      Write
    </Text>
    <Text slot="description">
      Read and write
      only
    </Text>
  </Item>
  <Item textValue="Admin">
    <Text slot="label">
      Admin
    </Text>
    <Text slot="description">
      Full access
    </Text>
  </Item>
</MySelect>

Controlled selection#

Setting a selected option can be done by using the defaultSelectedKey or selectedKey prop. The selected key corresponds to the id prop 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<React.Key>("Bison");

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

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

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

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

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

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/data';

interface Character {
  name: string
}

function AsyncLoadingExample() {
  let list = useAsyncList<Character>({
    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 (
    <MySelect label="Pick a Pokemon" items={list.items}>
      {(item) => <Item id={item.name}>{item.name}</Item>}
    </MySelect>
  );
}

import {useAsyncList} from '@react-stately/data';

interface Character {
  name: string
}

function AsyncLoadingExample() {
  let list = useAsyncList<Character>({
    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 (
    <MySelect label="Pick a Pokemon" items={list.items}>
      {(item) => <Item id={item.name}>{item.name}</Item>}
    </MySelect>
  );
}

import {useAsyncList} from '@react-stately/data';

interface Character {
  name: string;
}

function AsyncLoadingExample() {
  let list =
    useAsyncList<
      Character
    >({
      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 (
    <MySelect
      label="Pick a Pokemon"
      items={list.items}
    >
      {(item) => (
        <Item
          id={item.name}
        >
          {item.name}
        </Item>
      )}
    </MySelect>
  );
}

Disabled#

A Select can be fully disabled using the isDisabled prop.

<MySelect label="Choose frequency" isDisabled>
  <Item id="rarely">Rarely</Item>
  <Item id="sometimes">Sometimes</Item>

Disabled options#

Select supports marking items as disabled using the disabledKeys prop. Each key in this list corresponds with the id 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.

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

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>
      <MySelect label="Choose frequency" isOpen={open} onOpenChange={setOpen}>
        <Item id="rarely">Rarely</Item>
        <Item id="sometimes">Sometimes</Item>
        <Item id="always">Always</Item>
      </MySelect>
    </>
  );
}

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

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

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

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

Help text#

The description slot can be used to associate additional help text with a Select. Additionally, the errorMessage slot can be used to help the user fix a validation error. It should be combined with the validationState prop to semantically mark the Select as invalid for assistive technologies.

function Example() {
  let [animalId, setAnimalId] = React.useState<React.Key | null>(null);
  let options = [
    { id: 1, name: 'Aardvark' },
    { id: 2, name: 'Cat' },

Advanced customization#

Composition#

If you need to customize one of the components within a Select, such as Button or ListBox, in many cases you can create a wrapper component. This lets you customize the props passed to the component.

function MyListBox(props) {
  return <ListBox {...props} className="my-listbox" />
}

function MyListBox(props) {
  return <ListBox {...props} className="my-listbox" />
}

function MyListBox(
  props
) {
  return (
    <ListBox
      {...props}
      className="my-listbox"
    />
  );
}

Hooks#

If you need to customize things even further, such as accessing internal state or customizing DOM structure, you can drop down to the lower level Hook-based API. Select sends props to its child elements via public React contexts for each component. You can use this context to implement replacements for any component, using hooks from react-aria. This allows you to replace only the components you need to customize, and keep using the others.

Select uses the following hooks. See the linked documentation for more details.

To replace a component used within a Select, create your own component and use the useContextProps hook to merge the local props and ref with the ones sent via context by Select. This example shows how you could implement a custom ListBox component that works with Select.

import {ListBoxContext, useContextProps} from 'react-aria-components';
import {useListBox} from 'react-aria';

function MyListBox(props) {
  // Merge local props and ref with props from context.
  let ref = React.useRef();
  [props, ref] = useContextProps(props, ref, ListBoxContext);

  // Get state sent from Select via context, and call useListBox.
  let {state} = React.useContext(ListBoxContext);
  let {listBoxProps} = useListBox(props, state, ref);

  // Render stuff
  // ...
}

import {
  ListBoxContext,
  useContextProps
} from 'react-aria-components';
import {useListBox} from 'react-aria';

function MyListBox(props) {
  // Merge local props and ref with props from context.
  let ref = React.useRef();
  [props, ref] = useContextProps(
    props,
    ref,
    ListBoxContext
  );

  // Get state sent from Select via context, and call useListBox.
  let { state } = React.useContext(ListBoxContext);
  let { listBoxProps } = useListBox(props, state, ref);

  // Render stuff
  // ...
}

import {
  ListBoxContext,
  useContextProps
} from 'react-aria-components';
import {useListBox} from 'react-aria';

function MyListBox(
  props
) {
  // Merge local props and ref with props from context.
  let ref = React
    .useRef();
  [props, ref] =
    useContextProps(
      props,
      ref,
      ListBoxContext
    );

  // Get state sent from Select via context, and call useListBox.
  let { state } = React
    .useContext(
      ListBoxContext
    );
  let { listBoxProps } =
    useListBox(
      props,
      state,
      ref
    );

  // Render stuff
  // ...
}

This also works the other way. If you need to customize Select itself, but want to reuse the components it contains, you can do so by providing the necessary contexts. The Provider component is an easier way to send multiple contexts at once.

import {ButtonContext, LabelContext, ListBoxContext, PopoverContext, Provider} from 'react-aria-components';
import {useSelect} from 'react-aria';

function MySelect(props) {
  // ...
  let ref = useRef(null);
  let {
    labelProps,
    triggerProps,
    valueProps,
    menuProps
  } = useSelect({/* ... */});

  return (
    <Provider
      values={[
        [LabelContext, labelProps],
        [ButtonContext, { ...triggerProps, ref }],
        [PopoverContext, { state, triggerRef: ref }],
        [ListBoxContext, { ...listBoxProps, ref: listBoxRef }]
      ]}
    >
      {props.children}
    </Provider>
  );
}

import {
  ButtonContext,
  LabelContext,
  ListBoxContext,
  PopoverContext,
  Provider
} from 'react-aria-components';
import {useSelect} from 'react-aria';

function MySelect(props) {
  // ...
  let ref = useRef(null);
  let {
    labelProps,
    triggerProps,
    valueProps,
    menuProps
  } = useSelect({/* ... */});

  return (
    <Provider
      values={[
        [LabelContext, labelProps],
        [ButtonContext, { ...triggerProps, ref }],
        [PopoverContext, { state, triggerRef: ref }],
        [ListBoxContext, {
          ...listBoxProps,
          ref: listBoxRef
        }]
      ]}
    >
      {props.children}
    </Provider>
  );
}

import {
  ButtonContext,
  LabelContext,
  ListBoxContext,
  PopoverContext,
  Provider
} from 'react-aria-components';
import {useSelect} from 'react-aria';

function MySelect(
  props
) {
  // ...
  let ref = useRef(null);
  let {
    labelProps,
    triggerProps,
    valueProps,
    menuProps
  } = useSelect({
    /* ... */
  });

  return (
    <Provider
      values={[
        [
          LabelContext,
          labelProps
        ],
        [ButtonContext, {
          ...triggerProps,
          ref
        }],
        [
          PopoverContext,
          {
            state,
            triggerRef:
              ref
          }
        ],
        [
          ListBoxContext,
          {
            ...listBoxProps,
            ref:
              listBoxRef
          }
        ]
      ]}
    >
      {props.children}
    </Provider>
