}Features#
A combo box can be built using the <datalist> HTML element, but this is very limited in functionality and difficult to style. ComboBox helps achieve accessible combo box and autocomplete components that can be styled as needed.
- Flexible – Support for selecting pre-defined values, custom values, controlled and uncontrolled state, custom filter functions, async loading, disabled items, validation, and multiple menu trigger options.
- Keyboard navigation – ComboBox can be opened and navigated using the arrow keys, along with page up/down, home/end, etc. The list of options is filtered while typing into the input, and items can be selected with the enter key.
- Accessible – Follows the ARIA combobox pattern, with support for items and sections, and slots for label and description elements within each item. Custom localized announcements are included for option focusing, filtering, and selection using an ARIA live region to ensure announcements are clear and consistent.
- Validation – Support for native HTML constraint validation with customizable UI, custom validation functions, realtime validation, and server-side validation errors.
- Styleable – Items include builtin states for styling, such as hover, press, focus, selected, and disabled.
Read our blog post for more details about the interactions and accessibility features implemented by ComboBox.
Anatomy#
A combo box consists of a label, an input which displays the current value, a listbox displayed in a popover, and an optional button
used to toggle the popover open state. Users can type within the input to filter the available options
within the list box. The list box popover may be opened by a variety of input field interactions specified
by the menuTrigger prop provided to ComboBox, or by clicking or touching the button.
ComboBox 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.

identify it to assistive technology.
Concepts#
ComboBox makes use of the following concepts:
Composed components#
A ComboBox uses the following components, which may also be used standalone or reused in other components.
Examples#
Starter kits#
To help kick-start your project, we offer starter kits that include example implementations of all React Aria components with various styling solutions. All components are fully styled, including support for dark mode, high contrast mode, and all UI states. Each starter comes with a pre-configured Storybook that you can experiment with, or use as a starting point for your own component library.
Reusable wrappers#
If you will use a ComboBox 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 ComboBox 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 slot to render help text, and FieldError component to render validation errors. The Item component is also wrapped to apply class names based on the current state, as described in the styling section.

ComboBox 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 ComboBox using the defaultItems 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.
import type {Key} from 'react-aria-components';
function Example() {
let options = [
{id: 1, name: 'Aerospace'},
{id: 2, name: 'Mechanical'},
{id: 3, name: 'Civil'},

Value#
A ComboBox's value is empty by default, but an initial, uncontrolled, value can be provided using the defaultInputValue prop.
Alternatively, a controlled value can be provided using the inputValue prop. Note that the input value of the ComboBox does not affect
the ComboBox's selected option.
function Example() {
let options = [
{id: 1, name: 'Adobe Photoshop'},
{id: 2, name: 'Adobe XD'},
{id: 3, name: 'Adobe InDesign'},
{id: 4, name: 'Adobe AfterEffects'},
{id: 5, name: 'Adobe Illustrator'},
{id: 6, name: 'Adobe Lightroom'},
{id: 7, name: 'Adobe Premiere Pro'},
{id: 8, name: 'Adobe Fresco'},
{id: 9, name: 'Adobe Dreamweaver'}
];
let [value, setValue] = React.useState('Adobe XD');

Custom values#
By default, ComboBox doesn't allow users to specify a value that doesn't exist in the list of options and will revert the input value to
the current selected value on blur. By specifying allowsCustomValue, this behavior is suppressed and the user is free to enter
any value within the field.
<MyComboBox label="Favorite Animal" allowsCustomValue>
<ListBoxItem id="red panda">Red Panda</ListBoxItem>
<ListBoxItem id="cat">Cat</ListBoxItem>
<ListBoxItem id="dog">Dog</ListBoxItem>

</MyComboBox>HTML forms#
ComboBox supports the name prop for integration with HTML forms. By default, the id of the selected item will be submitted to the server. If the formValue prop is set to "text" or the allowsCustomValue prop is true, the text in the input field will be submitted instead.

</div>Selection#
Setting a selected option can be done by using the defaultSelectedKey or selectedKey prop. The selected key corresponds to the id of an item. See Events for more details on selection events.

Links#
By default, interacting with an item in a ComboBox selects it and updates the input value. Alternatively, items may be links to another page or website. This can be achieved by passing the href prop to the <ListBoxItem> component. Interacting with link items navigates to the provided URL and does not update the selection or input value.

</MyComboBox>Client side routing#
The <ListBoxItem> component works with frameworks and client side routers like Next.js and React Router. As with other React Aria components that support links, this works via the RouterProvider component at the root of your app. See the client side routing guide to learn how to set this up.
Sections#
ComboBox 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.

Sections used with dynamic items are populated from a hierarchical data structure. Please note that Section takes an array of data using the items prop only. If the section also has a header,
the Collection component can be used to render the child items.

Text slots#
By default, items in a ComboBox are labeled by their text contents for accessibility. ListBoxItems also support the "label" and "description" slots to separate primary and secondary content, which improves screen reader announcements and can also be used for styling purposes.
Note: The ARIA spec prohibits listbox items from including interactive content such as buttons, checkboxes, etc.

</MyComboBox>Events#
ComboBox supports selection via mouse, keyboard, and touch. You can handle all of these via the onSelectionChange
prop. ComboBox will pass the selected id to the onSelectionChange handler.
Additionally, ComboBox accepts an onInputChange prop which is triggered whenever the value is edited by the user, whether through typing or option
selection.
The example below uses onSelectionChange and onInputChange to update the selection and input value stored in React state.
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'}
];
let [value, setValue] = React.useState('');
let [majorId, setMajorId] = React.useState('');
let onSelectionChange = (id) => {
setMajorId(id);
};
let onInputChange = (value) => {
setValue(value)
};
return (
<>
<p>Current selected major id: {majorId}</p>
<p>Current input text: {value}</p>
<MyComboBox

defaultItems={options}

{id: 4, name: 'Biomedical'},
{id: 5, name: 'Nuclear'},
{id: 6, name: 'Industrial'},
{id: 7, name: 'Chemical'},

Custom filtering#
By default, ComboBox uses a "contains" function from useFilter to filter the list of options. This can be overridden using the defaultFilter prop, or by using the items prop to control the filtered list. When items is provided rather than defaultItems, ComboBox does no filtering of its own.
The following example makes the inputValue controlled, and updates the filtered list that is passed to the items
prop when the input changes value.
import {useFilter} from 'react-aria';
function Example() {
let options = [
{ id: 1, email: 'fake@email.com' },
{ id: 2, email: 'anotherfake@email.com' },
{ id: 3, email: 'bob@email.com' },
{ id: 4, email: 'joe@email.com' },
{ id: 5, email: 'yourEmail@email.com' },
{ id: 6, email: 'valid@email.com' },
{ id: 7, email: 'spam@email.com' },
{ id: 8, email: 'newsletter@email.com' },
{ id: 9, email: 'subscribe@email.com' }
];
let { startsWith } = useFilter({ sensitivity: 'base' });
let [filterValue, setFilterValue] = React.useState('');
let filteredItems = React.useMemo(
() => options.filter((item) => startsWith(item.email, filterValue)),
[options, filterValue]
);
return (
<MyComboBox
label="To:"
items={filteredItems}
inputValue={filterValue}
onInputChange={setFilterValue} allowsCustomValue
>
{(item) => <ListBoxItem>{item.email}</ListBoxItem>}
</MyComboBox>
);
}
import {useFilter} from 'react-aria';
function Example() {
let options = [
{ id: 1, email: 'fake@email.com' },
{ id: 2, email: 'anotherfake@email.com' },
{ id: 3, email: 'bob@email.com' },
{ id: 4, email: 'joe@email.com' },
{ id: 5, email: 'yourEmail@email.com' },
{ id: 6, email: 'valid@email.com' },
{ id: 7, email: 'spam@email.com' },
{ id: 8, email: 'newsletter@email.com' },
{ id: 9, email: 'subscribe@email.com' }
];
let { startsWith } = useFilter({ sensitivity: 'base' });
let [filterValue, setFilterValue] = React.useState('');

Fully controlled#
When a ComboBox has multiple controlled properties (e.g.inputValue, selectedKey, items), it is important to note that an update to one of these properties will
not automatically update the others. Each interaction done in the ComboBox will only trigger its associated event handler. For example, typing in the field will only
trigger onInputChange whereas selecting an item from the ComboBox menu will only trigger onSelectionChange so it is your responsibility to update the other
controlled properties accordingly. Note that you should provide an onSelectionChange handler for a ComboBox with controlled input value and open state. This way, you can properly
control the menu's open state when the user selects an option or blurs from the field.
The below example demonstrates how you would construct the same example above in a completely controlled fashion.
function ControlledComboBox() {
let options = [
{id: 1, name: 'Aerospace'},
{id: 2, name: 'Mechanical'},
{id: 3, name: 'Civil'},
{id: 4, name: 'Biomedical'},

Menu trigger behavior#
ComboBox supports three different menuTrigger prop values:
input(default): ComboBox menu opens when the user edits the input text.focus: ComboBox menu opens when the user focuses the ComboBox input.manual: ComboBox menu only opens when the user presses the trigger button or uses the arrow keys.
The example below has menuTrigger set to focus.
<MyComboBox label="Favorite Animal" menuTrigger="focus">
<ListBoxItem id="red panda">Red Panda</ListBoxItem>
<ListBoxItem id="cat">Cat</ListBoxItem>
<ListBoxItem id="dog">Dog</ListBoxItem>
<ListBoxItem id="aardvark">Aardvark</ListBoxItem>
<ListBoxItem id="kangaroo">Kangaroo</ListBoxItem>
<ListBoxItem id="snake">Snake</ListBoxItem>

</MyComboBox>Asynchronous loading#
This example uses the useAsyncList hook to handle asynchronous loading and filtering 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. See this CodeSandbox for an example of a ComboBox supporting those features.
import {useAsyncList} from 'react-stately';
interface Character {
name: string;
}
function AsyncLoadingExample() {
let list = useAsyncList<Character>({
async load({ signal, filterText }) {
let res = await fetch(
`https://swapi.py4e.com/api/people/?search=`,
{ signal }
);
let json = await res.json();
return {
items: json.results
};
}
});
return (
<MyComboBox
label="Star Wars Character Lookup"
items={list.items}
inputValue={list.filterText}
onInputChange={list.setFilterText}
>
{(item) => <ListBoxItem id={item.name}>{item.name}</ListBoxItem>}
</MyComboBox>
);
}
import {useAsyncList} from 'react-stately';
interface Character {
name: string;
}
function AsyncLoadingExample() {
let list = useAsyncList<Character>({
async load({ signal, filterText }) {
let res = await fetch(
`https://swapi.py4e.com/api/people/?search=`,
{ signal }
);
let json = await res.json();
return {
items: json.results
};
}
});
return (
<MyComboBox
label="Star Wars Character Lookup"
items={list.items}
inputValue={list.filterText}
onInputChange={list.setFilterText}
>
{(item) => (
<ListBoxItem id={item.name}>
{item.name}
</ListBoxItem>
)}
</MyComboBox>
);
}
import {useAsyncList} from 'react-stately';
interface Character {
name: string;
}
function AsyncLoadingExample() {
let list =
useAsyncList<
Character
>({
async load(
{
signal,
filterText
}
) {
let res =
await fetch(
`https://swapi.py4e.com/api/people/?search=`,
{ signal }
);
let json =
await res
.json();
return {
items:
json.results
};
}
});
return (
<MyComboBox

items={list.items}
inputValue={list

onInputChange={list
.setFilterText}
>
{(item) => (
<ListBoxItem

</MyComboBox>
);
}
Disabled#
A ComboBox can be fully disabled using the isDisabled prop.
<MyComboBox label="Favorite Animal" isDisabled>
<ListBoxItem id="red panda">Panda</ListBoxItem>
<ListBoxItem id="cat">Cat</ListBoxItem>
<ListBoxItem id="dog">Dog</ListBoxItem>
</MyComboBox><MyComboBox label="Favorite Animal" isDisabled>

}
}
}Disabled options#
You can disable specific options by providing an array of keys to ComboBox
via the disabledKeys prop. This will prevent options with matching keys from being pressable and
receiving keyboard focus as shown in the example below. Note that you are responsible for the styling of disabled options.
<MyComboBox label="Favorite Animal" disabledKeys={['cat', 'kangaroo']}>
<ListBoxItem id="red panda">Red Panda</ListBoxItem>

</MyComboBox>Validation#
ComboBox supports the isRequired prop to ensure the user enters a value, as well as custom client and server-side validation. It can also be integrated with other form libraries. See the Forms guide to learn more.
To display validation errors, add a <FieldError> element as a child of the ComboBox. This allows you to render error messages from all of the above sources with consistent custom styles.

Popover#
A <Popover> is a container to hold the <ListBox> suggestions for a ComboBox. By default, it has a placement of bottom start within a <ComboBox>, but this and other positioning properties may be customized.
Show props
| Name | Type | Default | Description |
trigger | string | — | The name of the component that triggered the popover. This is reflected on the element
as the |
triggerRef | RefObject<Element | null> | — | The ref for the element which the popover positions itself with respect to. When used within a trigger component such as DialogTrigger, MenuTrigger, Select, etc., this is set automatically. It is only required when used standalone. |

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-ComboBox {
/* ... */
}.react-aria-ComboBox {
/* ... */
}.react-aria-ComboBox {
/* ... */
}A custom className can also be specified on any component. This overrides the default className provided by React Aria with your own.
<ComboBox className="my-combobox">
{/* ... */}
</ComboBox><ComboBox className="my-combobox">
{/* ... */}
</ComboBox><ComboBox className="my-combobox">
{/* ... */}
</ComboBox>In addition, some components support multiple UI states (e.g. pressed, hovered, etc.). React Aria components expose states using data attributes, which you can target in CSS selectors. For example:
.react-aria-ListBoxItem[data-selected] {
/* ... */
}
.react-aria-ListBoxItem[data-focused] {
/* ... */
}.react-aria-ListBoxItem[data-selected] {
/* ... */
}
.react-aria-ListBoxItem[data-focused] {
/* ... */
}.react-aria-ListBoxItem[data-selected] {
/* ... */
}
.react-aria-ListBoxItem[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.
<ListBoxItem
className={({ isSelected }) => isSelected ? 'bg-blue-400' : 'bg-gray-100'}
>
Item
</ListBoxItem><ListBoxItem
className={({ isSelected }) =>
isSelected ? 'bg-blue-400' : 'bg-gray-100'}
>
Item
</ListBoxItem><ListBoxItem
className={(
{ isSelected }
) =>
isSelected
? 'bg-blue-400'
: 'bg-gray-100'}
>
Item
</ListBoxItem>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.
<ListBoxItem>
{({isSelected}) => (
<>
{isSelected && <CheckmarkIcon />}
Item
</>
)}
</ListBoxItem><ListBoxItem>
{({isSelected}) => (
<>
{isSelected && <CheckmarkIcon />}
Item
</>
)}
</ListBoxItem><ListBoxItem>
{(
{ isSelected }
) => (
<>
{isSelected && (
<CheckmarkIcon />
)}
Item
</>
)}
</ListBoxItem>The states and selectors for each component used in a ComboBox are documented below.
ComboBox#
A ComboBox can be targeted with the .react-aria-ComboBox CSS selector, or by overriding with a custom className. It supports the following states:
| Name | CSS Selector | Description |
isOpen | [data-open] | Whether the combobox is currently open. |
isDisabled | [data-disabled] | Whether the combobox is disabled. |
isInvalid | [data-invalid] | Whether the combobox is invalid. |
isRequired | [data-required] | Whether the combobox is required. |
Label#
A Label can be targeted with the .react-aria-Label CSS selector, or by overriding with a custom className.
Input#
An Input can be targeted with the .react-aria-Input CSS selector, or by overriding with a custom className. It supports the following states:
| Name | CSS Selector | Description |
isHovered | [data-hovered] | Whether the input is currently hovered with a mouse. |
isFocused | [data-focused] | Whether the input is focused, either via a mouse or keyboard. |
isFocusVisible | [data-focus-visible] | Whether the input is keyboard focused. |
isDisabled | [data-disabled] | Whether the input is disabled. |
isInvalid | [data-invalid] | Whether the input is invalid. |
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 | [data-focused] | Whether the button is focused, either via a mouse or keyboard. |
isFocusVisible | [data-focus-visible] | Whether the button is keyboard focused. |
isDisabled | [data-disabled] | Whether the button is disabled. |
isPending | [data-pending] | Whether the button is currently in a pending state. |
Popover#
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 ComboBox in the DOM. It supports the following states and render props:
| Name | CSS Selector | Description |
trigger | [data-trigger="..."] | The name of the component that triggered the popover, e.g. "DialogTrigger" or "ComboBox". |
placement | [data-placement="left | right | top | bottom"] | The placement of the popover relative to the trigger. |
isEntering | [data-entering] | Whether the popover is currently entering. Use this to apply animations. |
isExiting | [data-exiting] | Whether the popover is currently exiting. Use this to apply animations. |
Within a ComboBox, the popover will have the data-trigger="ComboBox" attribute, which can be used to define combobox-specific styles. In addition, 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 combobox.
.react-aria-Popover[data-trigger=ComboBox] {
width: var(--trigger-width);
}.react-aria-Popover[data-trigger=ComboBox] {
width: var(--trigger-width);
}.react-aria-Popover[data-trigger=ComboBox] {
width: var(--trigger-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.
ListBoxItem#
A ListBoxItem can be targeted with the .react-aria-ListBoxItem 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 | [data-selected] | 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 | [data-disabled] | Whether the item is non-interactive, i.e. both selection and actions are disabled and the item may
not be focused. Dependent on |
selectionMode | [data-selection-mode="single | multiple"] | 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 ComboBox can be targeted with the [slot=description] and [slot=errorMessage] CSS selectors, or by adding a custom className.
FieldError#
A FieldError can be targeted with the .react-aria-FieldError CSS selector, or by overriding with a custom className. It supports the following render props:
| Name | Description |
isInvalid | Whether the input value is invalid. |
validationErrors | The current error messages for the input if it is invalid, otherwise an empty array. |
validationDetails | The native validation details for the input. |
Advanced customization#
Composition#
If you need to customize one of the components within a ComboBox, such as Input 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"
/>
);
}
Contexts#
All React Aria Components export a corresponding context that can be used to send props to them from a parent element. This enables you to build your own compositional APIs similar to those found in React Aria Components itself. You can send any prop or ref via context that you could pass to the corresponding component. The local props and ref on the component are merged with the ones passed via context, with the local props taking precedence (following the rules documented in mergeProps).
| Component | Context | Props | Ref |
ComboBox | ComboBoxContext | ComboBoxProps | HTMLDivElement |
This example shows a FieldGroup component that renders a group of filters with a title. The entire group can be marked as disabled via the isDisabled prop, which is passed to all child selects via the ComboBoxContext provider.
import {ComboBoxContext} from 'react-aria-components';
interface FieldGroupProps {
title?: string,
children?: React.ReactNode,
isDisabled?: boolean
}
function FieldGroup({title, children, isDisabled}: FieldGroupProps) {
return (
<fieldset>
<legend>{title}</legend>
<ComboBoxContext.Provider value={{isDisabled}}> {children}
</ComboBoxContext.Provider>
</fieldset>
);
}
<FieldGroup title="Filters" isDisabled>
<MyComboBox label="Status" defaultSelectedKey="published">
<ListBoxItem id="draft">Draft</ListBoxItem>
<ListBoxItem id="published">Published</ListBoxItem>
<ListBoxItem id="deleted">Deleted</ListBoxItem>
</MyComboBox>
<MyComboBox label="Author" defaultSelectedKey="emma">
<ListBoxItem id="john">John</ListBoxItem>
<ListBoxItem id="emma">Emma</ListBoxItem>
<ListBoxItem id="tim">Tim</ListBoxItem>
</MyComboBox>
</FieldGroup>import {ComboBoxContext} from 'react-aria-components';
interface FieldGroupProps {
title?: string;
children?: React.ReactNode;
isDisabled?: boolean;
}
function FieldGroup(
{ title, children, isDisabled }: FieldGroupProps
) {
return (
<fieldset>
<legend>{title}</legend>
<ComboBoxContext.Provider value={{ isDisabled }}> {children}
</ComboBoxContext.Provider>
</fieldset>
);
}
<FieldGroup title="Filters" isDisabled>

interface FieldGroupProps {
title?: string;
children?:
React.ReactNode;
isDisabled?: boolean;
}
function FieldGroup(
{
title,
children,
isDisabled
}: FieldGroupProps
) {
return (
<fieldset>

}Custom children#
ComboBox passes props to its child components, such as the label and input, via their associated contexts. These contexts are exported so you can also consume them in your own custom components. This enables you to reuse existing components from your app or component library together with React Aria Components.
| Component | Context | Props | Ref |
Label | LabelContext | LabelProps | HTMLLabelElement |
Button | ButtonContext | ButtonProps | HTMLButtonElement |
Input | InputContext | InputProps | HTMLInputElement |
Popover | PopoverContext | PopoverProps | HTMLElement |
ListBox | ListBoxContext | ListBoxProps | HTMLDivElement |
Text | TextContext | TextProps | HTMLElement |
This example consumes from LabelContext in an existing styled label component to make it compatible with React Aria Components. The useContextProps hook merges the local props and ref with the ones provided via context by ComboBox.
import type {LabelProps} from 'react-aria-components';
import {LabelContext, useContextProps} from 'react-aria-components';
const MyCustomLabel = React.forwardRef(
(props: LabelProps, ref: React.ForwardedRef<HTMLLabelElement>) => {
// Merge the local props and ref with the ones provided via context.
[props, ref] = useContextProps(props, ref, LabelContext);
// ... your existing Label component
return <label {...props} ref={ref} />;
}
);
import type {LabelProps} from 'react-aria-components';
import {
LabelContext,
useContextProps
} from 'react-aria-components';
const MyCustomLabel = React.forwardRef(
(
props: LabelProps,
ref: React.ForwardedRef<HTMLLabelElement>
) => {
// Merge the local props and ref with the ones provided via context.
[props, ref] = useContextProps(
props,
ref,
LabelContext
);
// ... your existing Label component
return <label {...props} ref={ref} />;
}
);
import type {LabelProps} from 'react-aria-components';
import {
LabelContext,
useContextProps
} from 'react-aria-components';
const MyCustomLabel =
React.forwardRef(
(
props: LabelProps,
ref:
React.ForwardedRef<
HTMLLabelElement
>
) => {
// Merge the local props and ref with the ones provided via context.
[props, ref] =
useContextProps(
props,
ref,
LabelContext
);
// ... your existing Label component
return (
<label
{...props}
ref={ref}
/>
);
}
);
Now you can use MyCustomLabel within a ComboBox, in place of the builtin React Aria Components Label.
<ComboBox>
<MyCustomLabel>Name</MyCustomLabel> {/* ... */}
</ComboBox><ComboBox>
<MyCustomLabel>Name</MyCustomLabel> {/* ... */}
</ComboBox><ComboBox>
<MyCustomLabel>
Name
</MyCustomLabel> {/* ... */}
</ComboBox>State#
ComboBox provides an ComboBoxState object to its children via ComboBoxStateContext. This can be used to access and manipulate the combo box's state.
This example shows a ComboBoxClearButton component that can be placed within a ComboBox to allow the user to clear the selected value.
import {ComboBoxStateContext} from 'react-aria-components';
function ComboBoxClearButton() {
let state = React.useContext(ComboBoxStateContext); return (
<Button
// Don't inherit default Button behavior from ComboBox.
slot={null}

onPress={() => state?.setSelectedKey(null)}>
