Features#
Checkbox groups can be built in HTML with the
<fieldset>
and <input> elements,
however these can be difficult to style. CheckboxGroup
helps achieve accessible
checkbox groups that can be styled as needed.
- Accessible – Checkbox groups are exposed to assistive technology via ARIA, and automatically associate a nested
<Label>
. Description and error message help text slots are supported as well. - HTML form integration – Each individual checkbox uses a visually hidden
<input>
element under the hood, which enables HTML form integration and autofill.
Anatomy#
A checkbox group consists of a set of checkboxes, and a label. Each checkbox includes a label and a visual selection indicator. Zero or more checkboxes within the group can be selected at a time. Users may click or touch a checkbox to select it, or use the Tab key to navigate to it and the Space key to toggle it.
CheckboxGroup
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
inputs via the aria-describedby
attribute.
Individual checkboxes must have a visual label. If the checkbox group does not have a visible label,
an aria-label
or aria-labelledby
prop must be passed instead to identify the element to assistive
technology.
Composed components#
A CheckboxGroup
uses the following components, which may also be used standalone or reused in other components.

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-CheckboxGroup {
/* ... */
}
.react-aria-CheckboxGroup {
/* ... */
}
.react-aria-CheckboxGroup {
/* ... */
}
A custom className
can also be specified on any component. This overrides the default className
provided by React Aria with your own.
<Checkbox className="my-checkbox">
{/* ... */}
</Checkbox>
<Checkbox className="my-checkbox">
{/* ... */}
</Checkbox>
<Checkbox className="my-checkbox">
{/* ... */}
</Checkbox>;
In addition, some components support multiple UI states (e.g. focused, placeholder, readonly, 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-Checkbox[data-selected] {
/* ... */
}
.react-aria-Checkbox[data-selected] {
/* ... */
}
.react-aria-Checkbox[data-selected] {
/* ... */
}
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.
<Checkbox
className={({ isPressed }) => isPressed ? 'bg-gray-700' : 'bg-gray-600'}
/>;
<Checkbox
className={({ isPressed }) =>
isPressed ? 'bg-gray-700' : 'bg-gray-600'}
/>;
<Checkbox
className={(
{ isPressed }
) =>
isPressed
? 'bg-gray-700'
: 'bg-gray-600'}
/>;
Render props may also be used as children to alter what elements are rendered based on the current state. For example, you could render an extra element when the checkbox is selected.
<Checkbox>
{({isSelected}) => (
<>
{isSelected && <CheckIcon />}
Subscribe
</>
)}
</Checkbox>
<Checkbox>
{({isSelected}) => (
<>
{isSelected && <CheckIcon />}
Subscribe
</>
)}
</Checkbox>
<Checkbox>
{({ isSelected }) => (
<>
{isSelected && (
<CheckIcon />
)}
Subscribe
</>
)}
</Checkbox>;
The states and selectors for each component used in a CheckboxGroup
are documented below.
CheckboxGroup#
A CheckboxGroup
can be targeted with the .react-aria-CheckboxGroup
CSS selector, or by overriding with a custom className
. It supports the following states and render props:
Name | CSS Selector | Description |
isDisabled | [aria-disabled] | Whether the checkbox group is disabled. |
isReadOnly | [data-readonly] | Whether the checkbox group is read only. |
isRequired | [data-required] | Whether the checkbox group is required. |
validationState | [data-validation-state="invalid" | "valid"] | The validation state of the checkbox group. |
Checkbox#
A Checkbox
can be targeted with the .react-aria-Checkbox
CSS selector, or by overriding with a custom className
. It supports the following states:
Name | CSS Selector | Description |
isSelected | [data-selected] | Whether the checkbox is selected. |
isIndeterminate | [data-indeterminate] | Whether the checkbox is selected. |
isHovered | [data-hovered] | Whether the checkbox is currently hovered with a mouse. |
isPressed | [data-pressed] | Whether the checkbox is currently in a pressed state. |
isFocused | [data-focused] | Whether the checkbox is focused, either via a mouse or keyboard. |
isFocusVisible | [data-focus-visible] | Whether the checkbox is keyboard focused. |
isDisabled | [data-disabled] | Whether the checkbox is disabled. |
isReadOnly | [data-readonly] | Whether the checkbox is read only. |
validationState | [data-validation-state="valid | invalid"] | Whether the checkbox is valid or invalid. |
isRequired | [data-required] | Whether the checkbox is required. |
Text#
The help text elements within a CheckboxGroup
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 CheckboxGroup 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 CheckboxGroup
and all of its children together into a single component which accepts a label
prop, which is passed to the right place. It also shows how to use the description
and errorMessage
slots to render help text (see below for details).
import {Text} from 'react-aria-components';
function MyCheckboxGroup({
label,
description,
errorMessage,
children,
...props
}) {
return (
<CheckboxGroup {...props}>
{label}
{children}
{description && <Text slot="description">{description}</Text>}
{errorMessage && <Text slot="errorMessage">{errorMessage}</Text>}
</CheckboxGroup>
);
}
function MyCheckbox({children, ...props}) {
return (
<Checkbox {...props}>
<div className="checkbox">
<svg viewBox="0 0 18 18"><polyline points="1 9 7 14 15 4" /></svg>
</div>
{children}
</Checkbox>
);
}
<MyCheckboxGroup label="Favorite sports">
<MyCheckbox value="soccer">Soccer</MyCheckbox>
<MyCheckbox value="baseball">Baseball</MyCheckbox>
<MyCheckbox value="basketball">Basketball</MyCheckbox>
</MyCheckboxGroup>
import {Text} from 'react-aria-components';
function MyCheckboxGroup({
label,
description,
errorMessage,
children,
...props
}) {
return (
<CheckboxGroup {...props}>
{label}
{children}
{description && (
<Text slot="description">{description}</Text>
)}
{errorMessage && (
<Text slot="errorMessage">{errorMessage}</Text>
)}
</CheckboxGroup>
);
}
function MyCheckbox({ children, ...props }) {
return (
<Checkbox {...props}>
<div className="checkbox">
<svg viewBox="0 0 18 18">
<polyline points="1 9 7 14 15 4" />
</svg>

</MyCheckboxGroup>
Usage#
The following examples show how to use the MyCheckboxGroup
and MyCheckbox
components created in the above example.
Default value#
An initial, uncontrolled value can be provided to the CheckboxGroup using the defaultValue
prop, which accepts an array of selected items that map to the
value
prop on each Checkbox.
<MyCheckboxGroup
label="Favorite sports (uncontrolled)"
defaultValue={['soccer', 'baseball']}
>
<MyCheckbox value="soccer">Soccer</MyCheckbox>
<MyCheckbox value="baseball">Baseball</MyCheckbox>
<MyCheckbox value="basketball">Basketball</MyCheckbox>
</MyCheckboxGroup>
<MyCheckboxGroup
label="Favorite sports (uncontrolled)"
defaultValue={['soccer', 'baseball']}
>
<MyCheckbox value="soccer">Soccer</MyCheckbox>
<MyCheckbox value="baseball">Baseball</MyCheckbox>
<MyCheckbox value="basketball">Basketball</MyCheckbox>
</MyCheckboxGroup>
<MyCheckboxGroup
label="Favorite sports (uncontrolled)"
defaultValue={[
'soccer',
'baseball'
]}
>
<MyCheckbox value="soccer">
Soccer
</MyCheckbox>
<MyCheckbox value="baseball">
Baseball
</MyCheckbox>
<MyCheckbox value="basketball">
Basketball
</MyCheckbox>
</MyCheckboxGroup>
Controlled value#
A controlled value can be provided using the value
prop, which accepts an array of selected items, which map to the
value
prop on each Checkbox. The onChange
event is fired when the user checks or unchecks an option. It receives a new array
containing the updated selected values.
function Example() {
let [selected, setSelected] = React.useState(['soccer', 'baseball']);
return (
<MyCheckboxGroup
label="Favorite sports (controlled)"
value={selected}
onChange={setSelected}
>
<MyCheckbox value="soccer">Soccer</MyCheckbox>
<MyCheckbox value="baseball">Baseball</MyCheckbox>
<MyCheckbox value="basketball">Basketball</MyCheckbox>
</MyCheckboxGroup>
);
}
function Example() {
let [selected, setSelected] = React.useState([
'soccer',
'baseball'
]);
return (
<MyCheckboxGroup
label="Favorite sports (controlled)"
value={selected}
onChange={setSelected}
>
<MyCheckbox value="soccer">Soccer</MyCheckbox>
<MyCheckbox value="baseball">Baseball</MyCheckbox>
<MyCheckbox value="basketball">Basketball</MyCheckbox>
</MyCheckboxGroup>
);
}
function Example() {
let [
selected,
setSelected
] = React.useState([
'soccer',
'baseball'
]);
return (
<MyCheckboxGroup
label="Favorite sports (controlled)"
value={selected}
onChange={setSelected}
>
<MyCheckbox value="soccer">
Soccer
</MyCheckbox>
<MyCheckbox value="baseball">
Baseball
</MyCheckbox>
<MyCheckbox value="basketball">
Basketball
</MyCheckbox>
</MyCheckboxGroup>
);
}
Group validation#
CheckboxGroups can display a validation state to communicate to the user if the current value is invalid.
Implement your own validation logic in your app and pass "invalid"
to the validationState
prop to either
the CheckboxGroup
or an individual Checkbox
to mark it as invalid.
If the group as a whole is invalid, for example if the user must choose at least one option but failed
to do so, then pass validationState="invalid"
to the CheckboxGroup
.
The following example shows how to require that at least one option is selected. It sets the validationState
prop to "invalid"
when no options are selected and removes it otherwise.
function Example() {
let [selected, setSelected] = React.useState([]);
return (
<MyCheckboxGroup
label="Sandwich condiments"
value={selected}
onChange={setSelected}
isRequired
validationState={selected.length === 0 ? 'invalid' : null}
>
<MyCheckbox value="lettuce">Lettuce</MyCheckbox>
<MyCheckbox value="tomato">Tomato</MyCheckbox>
<MyCheckbox value="onion">Onion</MyCheckbox>
<MyCheckbox value="sprouts">Sprouts</MyCheckbox>
</MyCheckboxGroup>
);
}
function Example() {
let [selected, setSelected] = React.useState([]);
return (
<MyCheckboxGroup
label="Sandwich condiments"
value={selected}
onChange={setSelected}
isRequired
validationState={selected.length === 0
? 'invalid'
: null}
>
<MyCheckbox value="lettuce">Lettuce</MyCheckbox>
<MyCheckbox value="tomato">Tomato</MyCheckbox>
<MyCheckbox value="onion">Onion</MyCheckbox>
<MyCheckbox value="sprouts">Sprouts</MyCheckbox>
</MyCheckboxGroup>
);
}
function Example() {
let [
selected,
setSelected
] = React.useState([]);
return (
<MyCheckboxGroup
label="Sandwich condiments"
value={selected}
onChange={setSelected}
isRequired
validationState={selected
.length === 0
? 'invalid'
: null}
>
<MyCheckbox value="lettuce">
Lettuce
</MyCheckbox>
<MyCheckbox value="tomato">
Tomato
</MyCheckbox>
<MyCheckbox value="onion">
Onion
</MyCheckbox>
<MyCheckbox value="sprouts">
Sprouts
</MyCheckbox>
</MyCheckboxGroup>
);
}
Individual Checkbox validation#
If an individual checkbox is invalid, for example if the user must select a particular option but failed
to do so, then pass validationState="invalid"
to the Checkbox
element instead.
The following example shows how to require that all items are selected. It uses the isRequired
prop on each individual Checkbox
element to indicate to assistive technology that every checkbox is required. By default, the isRequired
prop on the CheckboxGroup
only
indicates that the group is required, not any individual option. In addition, validationState="invalid"
is set on each checkbox that is not yet checked.
function Example() {
let [selected, setSelected] = React.useState([]);
return (
<MyCheckboxGroup
label="Agree to the following"
isRequired
value={selected}
onChange={setSelected}
>
<MyCheckbox
value="terms"
isRequired
validationState={!selected.includes('terms') ? 'invalid' : null}
>
Terms and conditions
</MyCheckbox>
<MyCheckbox
value="privacy"
isRequired
validationState={!selected.includes('privacy') ? 'invalid' : null}
>
Privacy policy
</MyCheckbox>
<MyCheckbox
value="cookies"
isRequired
validationState={!selected.includes('cookies') ? 'invalid' : null}
>
Cookie policy
</MyCheckbox>
</MyCheckboxGroup>
);
}
function Example() {
let [selected, setSelected] = React.useState([]);
return (
<MyCheckboxGroup
label="Agree to the following"
isRequired
value={selected}
onChange={setSelected}
>
<MyCheckbox
value="terms"
isRequired
validationState={!selected.includes('terms')
? 'invalid'
: null}
>
Terms and conditions
</MyCheckbox>
<MyCheckbox
value="privacy"
isRequired
validationState={!selected.includes('privacy')
? 'invalid'
: null}
>
Privacy policy
</MyCheckbox>
<MyCheckbox
value="cookies"
isRequired
validationState={!selected.includes('cookies')
? 'invalid'
: null}
>
Cookie policy
</MyCheckbox>
</MyCheckboxGroup>
);
}
function Example() {
let [
selected,
setSelected
] = React.useState([]);
return (
<MyCheckboxGroup
label="Agree to the following"
isRequired
value={selected}
onChange={setSelected}
>
<MyCheckbox
value="terms"
isRequired
validationState={!selected
.includes(
'terms'
)
? 'invalid'
: null}
>
Terms and
conditions
</MyCheckbox>
<MyCheckbox
value="privacy"
isRequired
validationState={!selected
.includes(
'privacy'
)
? 'invalid'
: null}
>
Privacy policy
</MyCheckbox>
<MyCheckbox
value="cookies"
isRequired
validationState={!selected
.includes(
'cookies'
)
? 'invalid'
: null}
>
Cookie policy
</MyCheckbox>
</MyCheckboxGroup>
);
}
Help text#
The description
slot can be used to associate additional help text with a checkbox group. 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 checkbox group as invalid for assistive technologies.
function Example() {
let [checked, setChecked] = React.useState(['dogs', 'dragons']);
let isValid = checked.length === 2 && checked.includes('dogs') &&
checked.includes('dragons');
return (
<MyCheckboxGroup
label="Pets"
onChange={setChecked}
value={checked}
validationState={isValid ? 'valid' : 'invalid'}
description={isValid ? 'Select your pets.' : null}
errorMessage={isValid
? null
: checked.includes('cats')
? 'No cats allowed.'
: 'Select only dogs and dragons.'}
>
<MyCheckbox value="dogs">Dogs</MyCheckbox>
<MyCheckbox value="cats">Cats</MyCheckbox>
<MyCheckbox value="dragons">Dragons</MyCheckbox>
</MyCheckboxGroup>
);
}
function Example() {
let [checked, setChecked] = React.useState([
'dogs',
'dragons'
]);
let isValid = checked.length === 2 &&
checked.includes('dogs') && checked.includes('dragons');
return (
<MyCheckboxGroup
label="Pets"
onChange={setChecked}
value={checked}
validationState={isValid ? 'valid' : 'invalid'}
description={isValid ? 'Select your pets.' : null}
errorMessage={isValid
? null
: checked.includes('cats')
? 'No cats allowed.'
: 'Select only dogs and dragons.'}
>
<MyCheckbox value="dogs">Dogs</MyCheckbox>
<MyCheckbox value="cats">Cats</MyCheckbox>
<MyCheckbox value="dragons">Dragons</MyCheckbox>
</MyCheckboxGroup>
);
}
function Example() {
let [
checked,
setChecked
] = React.useState([
'dogs',
'dragons'
]);
let isValid =
checked.length ===
2 &&
checked.includes(
'dogs'
) &&
checked.includes(
'dragons'
);
return (
<MyCheckboxGroup
label="Pets"
onChange={setChecked}
value={checked}
validationState={isValid
? 'valid'
: 'invalid'}
description={isValid
? 'Select your pets.'
: null}
errorMessage={isValid
? null
: checked
.includes(
'cats'
)
? 'No cats allowed.'
: 'Select only dogs and dragons.'}
>
<MyCheckbox value="dogs">
Dogs
</MyCheckbox>
<MyCheckbox value="cats">
Cats
</MyCheckbox>
<MyCheckbox value="dragons">
Dragons
</MyCheckbox>
</MyCheckboxGroup>
);
}
Disabled#
The entire CheckboxGroup can be disabled with the isDisabled
prop.
<MyCheckboxGroup label="Favorite sports" isDisabled>
<MyCheckbox value="soccer">Soccer</MyCheckbox>
<MyCheckbox value="baseball">Baseball</MyCheckbox>
<MyCheckbox value="basketball">Basketball</MyCheckbox>
</MyCheckboxGroup>
<MyCheckboxGroup label="Favorite sports" isDisabled>
<MyCheckbox value="soccer">Soccer</MyCheckbox>
<MyCheckbox value="baseball">Baseball</MyCheckbox>
<MyCheckbox value="basketball">Basketball</MyCheckbox>
</MyCheckboxGroup>
<MyCheckboxGroup
label="Favorite sports"
isDisabled
>
<MyCheckbox value="soccer">
Soccer
</MyCheckbox>
<MyCheckbox value="baseball">
Baseball
</MyCheckbox>
<MyCheckbox value="basketball">
Basketball
</MyCheckbox>
</MyCheckboxGroup>
To disable an individual checkbox, pass isDisabled
to the Checkbox
instead.
<MyCheckboxGroup label="Favorite sports">
<MyCheckbox value="soccer">Soccer</MyCheckbox>
<MyCheckbox value="baseball" isDisabled>Baseball</MyCheckbox>
<MyCheckbox value="basketball">Basketball</MyCheckbox>
</MyCheckboxGroup>
<MyCheckboxGroup label="Favorite sports">
<MyCheckbox value="soccer">Soccer</MyCheckbox>
<MyCheckbox value="baseball" isDisabled>
Baseball
</MyCheckbox>
<MyCheckbox value="basketball">Basketball</MyCheckbox>
</MyCheckboxGroup>
<MyCheckboxGroup label="Favorite sports">
<MyCheckbox value="soccer">
Soccer
</MyCheckbox>
<MyCheckbox
value="baseball"
isDisabled
>
Baseball
</MyCheckbox>
<MyCheckbox value="basketball">
Basketball
</MyCheckbox>
</MyCheckboxGroup>
Read only#
The isReadOnly
prop makes the selection immutable. Unlike isDisabled
, the CheckboxGroup remains focusable.
See the MDN docs for more information.
<MyCheckboxGroup
label="Favorite sports"
defaultValue={['baseball']}
isReadOnly
>
<MyCheckbox value="soccer">Soccer</MyCheckbox>
<MyCheckbox value="baseball">Baseball</MyCheckbox>
<MyCheckbox value="basketball">Basketball</MyCheckbox>
</MyCheckboxGroup>
<MyCheckboxGroup
label="Favorite sports"
defaultValue={['baseball']}
isReadOnly
>
<MyCheckbox value="soccer">Soccer</MyCheckbox>
<MyCheckbox value="baseball">Baseball</MyCheckbox>
<MyCheckbox value="basketball">Basketball</MyCheckbox>
</MyCheckboxGroup>
<MyCheckboxGroup
label="Favorite sports"
defaultValue={[
'baseball'
]}
isReadOnly
>
<MyCheckbox value="soccer">
Soccer
</MyCheckbox>
<MyCheckbox value="baseball">
Baseball
</MyCheckbox>
<MyCheckbox value="basketball">
Basketball
</MyCheckbox>
</MyCheckboxGroup>
HTML forms#
CheckboxGroup supports the name
prop, paired with the Checkbox value
prop, for integration with HTML forms.
<MyCheckboxGroup label="Favorite sports" name="sports">
<MyCheckbox value="soccer">Soccer</MyCheckbox>
<MyCheckbox value="baseball">Baseball</MyCheckbox>
<MyCheckbox value="basketball">Basketball</MyCheckbox>
</MyCheckboxGroup>
<MyCheckboxGroup label="Favorite sports" name="sports">
<MyCheckbox value="soccer">Soccer</MyCheckbox>
<MyCheckbox value="baseball">Baseball</MyCheckbox>

</MyCheckbox>
<MyCheckbox value="basketball">
Basketball
</MyCheckbox>
</MyCheckboxGroup>
