API#
useToggleButton(
props: AriaToggleButtonOptions<ElementType>,
state: ToggleState,
ref: RefObject<any>
): ToggleButtonAria<HTMLAttributes<any>>
Features#
Toggle buttons are similar to action buttons, but support an additional selection state that is toggled when a user presses the button. There is no built-in HTML element that represents a toggle button, so React Aria implements it using ARIA attributes.
- Native HTML
<button>
,<a>
, and custom element type support - Exposed as a toggle button via ARIA
- Mouse and touch event handling, and press state management
- Keyboard focus management and cross browser normalization
- Keyboard event support for Space and Enter keys
Anatomy#
Toggle buttons consist of a clickable area usually containing a textual label or an icon that users can click to toggle a selection state. In addition, keyboard users may toggle the state using the Space or Enter keys.
useToggleButton
returns props to be spread onto the button element, along with a boolean indicating
whether the user is currently pressing the button:
Name | Type | Description |
isSelected | boolean | Whether the button is selected. |
isDisabled | boolean | Whether the button is disabled. |
buttonProps | T | Props for the button element. |
isPressed | boolean | Whether the button is currently pressed. |
Selection state is managed by the useToggleState
hook in @react-stately/toggle
. The state object should be passed as an option to useToggleButton
.
If a visual label is not provided (e.g. an icon only button), then an aria-label
or
aria-labelledby
prop must be passed to identify the button to assistive technology.
Example#
By default, useToggleButton
assumes that you are using it with a native <button>
element. You can use a custom
element type by passing the elementType
prop to useToggleButton
. See the useButton
docs for an example of this.
The following example shows how to use the useToggleButton
and useToggleState
hooks to build a toggle button.
The toggle state is used to switch between a green and blue background when unselected and selected respectively.
In addition, the isPressed
state is used to adjust the background to be darker when the user presses down on the button.
import {useToggleState} from 'react-stately';
import {useToggleButton} from 'react-aria';
import {useRef} from 'react';
function ToggleButton(props) {
let ref = useRef<HTMLButtonElement | null>(null);
let state = useToggleState(props);
let { buttonProps, isPressed } = useToggleButton(props, state, ref);
return (
<button
{...buttonProps}
style={{
background: isPressed
? state.isSelected ? 'darkgreen' : 'gray'
: state.isSelected
? 'green'
: 'lightgray',
color: state.isSelected ? 'white' : 'black',
padding: 10,
fontSize: 16,
userSelect: 'none',
WebkitUserSelect: 'none',
border: 'none'
}}
ref={ref}
>
{props.children}
</button>
);
}

Usage#
The following examples show how to use the ToggleButton
component created in the above example.
Controlled selection state#
A default selection state for a toggle button can be set using the defaultSelected
prop, or controlled with the isSelected
prop. The onChange
event is fired when the user presses the button, toggling the boolean. See React's documentation on
uncontrolled components for more info.
function Example() {
let [isSelected, setSelected] = React.useState(false);
return (
<ToggleButton
isSelected={isSelected}
onChange={setSelected}
aria-label="Star">
★
</ToggleButton>
);
}
function Example() {
let [isSelected, setSelected] = React.useState(false);
return (
<ToggleButton
isSelected={isSelected}
onChange={setSelected}
aria-label="Star">
★
</ToggleButton>
);
}
function Example() {
let [
isSelected,
setSelected
] = React.useState(
false
);
return (
<ToggleButton
isSelected={isSelected}
onChange={setSelected}
aria-label="Star"
>
★
</ToggleButton>
);
}
Disabled#
A ToggleButton
can be disabled using the isDisabled
prop.
<ToggleButton isDisabled>Pin</ToggleButton>
<ToggleButton isDisabled>Pin</ToggleButton>
<ToggleButton
isDisabled
>
Pin
</ToggleButton>
