API#

useSlider<T extends number | number[]>(
  props: AriaSliderProps<T>,
  state: SliderState,
  trackRef: RefObject<Element>
): SliderAria

useSliderThumb(
  (opts: AriaSliderThumbOptions,
  , state: SliderState
)): SliderThumbAria

Features#

The <input type="range"> HTML element can be used to build a slider, however it is very difficult to style cross browser. useSlider and useSliderThumb help achieve accessible sliders that can be styled as needed.

Support for one or multiple thumbs
Support for mouse, touch, and keyboard via the useMove hook
Multi-touch support for dragging multiple thumbs or multiple sliders at once
Pressing on the track moves the nearest thumb to that position
Supports using the arrow keys, as well as page up/down, home, and end keys
Support for both horizontal and vertical orientations
Support for custom min, max, and step values with handling for rounding errors
Support for disabling the whole slider or individual thumbs
Prevents text selection while dragging
Exposed to assistive technology as a group of slider elements via ARIA
Slider thumbs use hidden native input elements to support touch screen readers
Support for labeling both the slider as a whole and individual thumbs
Support for displaying the current thumb values using an <output> element
Internationalized number formatting as a percentage or value
Support for mirroring in RTL locales

Anatomy#

Sliders consist of a track element showing the range of available values, one or more thumbs showing the current values, an optional <output> element displaying the current values textually, and a label. The thumbs can be dragged to allow a user to change their value. In addition, the track can be clicked to move the nearest thumb to that position.

useSlider hook#

useSlider returns several sets of props and you should spread each one onto the appropriate element:

Name	Type	Description
`labelProps`	`LabelHTMLAttributes<HTMLLabelElement>`	Props for the label element.
`groupProps`	`DOMAttributes`	Props for the root element of the slider component; groups slider inputs.
`trackProps`	`DOMAttributes`	Props for the track element.
`outputProps`	`OutputHTMLAttributes<HTMLOutputElement>`	Props for the output element, displaying the value of the slider thumbs.

If there is no visual label, an aria-label or aria-labelledby prop must be passed instead to identify the element to screen readers.

useSliderThumb hook#

useSliderThumb returns props that you should spread onto the appropriate elements, along with states for styling:

Name	Type	Description
`thumbProps`	`DOMAttributes`	Props for the root thumb element; handles the dragging motion.
`inputProps`	`InputHTMLAttributes<HTMLInputElement>`	Props for the visually hidden range input element.
`labelProps`	`LabelHTMLAttributes<HTMLLabelElement>`	Props for the label element for this thumb (optional).
`isDragging`	`boolean`	Whether this thumb is currently being dragged.
`isFocused`	`boolean`	Whether the thumb is currently focused.
`isDisabled`	`boolean`	Whether the thumb is disabled.

If there is no visual label, an aria-label or aria-labelledby prop must be passed instead to identify each thumb to screen readers.

Slider state is managed by the useSliderState hook.

Examples#

Single thumb#

This example shows how to build a simple horizontal slider with a single thumb. In addition, it includes a label which can be clicked to focus the slider thumb, and an <output> element to display the current slider value as text. This is formatted using a locale aware number formatter provided by the useNumberFormatter hook.

The <input> element inside the thumb is used to represent the slider to assistive technology, and is hidden from view using the VisuallyHidden component. The thumb also uses the useFocusRing hook to display using a different color when it is keyboard focused (try tabbing to it).

Multi thumb#

This example shows how to build a slider with multiple thumbs. The thumb component is the same one shown in the previous example. The main difference in this example is that there are two <Thumb> elements rendered with different index props. In addition, the <output> element uses state.getThumbValueLabel for each thumb to display the selected range.

function RangeSlider(props) {
  let trackRef = React.useRef(null);

  let numberFormatter = useNumberFormatter(props.formatOptions);
  let state = useSliderState({ ...props, numberFormatter });
  let {
    groupProps,
    trackProps,
    labelProps,
    outputProps
  } = useSlider(props, state, trackRef);

  return (
    <div {...groupProps} className={`slider ${state.orientation}`}>
      {props.label &&
        (
          <div className="label-container">
            <label {...labelProps}>{props.label}</label>
            <output {...outputProps}>
              {`${state.getThumbValueLabel(0)} - ${
                state.getThumbValueLabel(1)
              }`}
            </output>
          </div>
        )}

Usage#

The following examples show how to use the Slider and RangeSlider components created in the above examples.

Vertical orientation#

Sliders are horizontally oriented by default. The orientation prop can be set to "vertical" to create a vertical slider. This example also uses aria-label rather than label to create a slider with no visible label.

<Slider
  orientation="vertical"
  aria-label="Opacity"
  maxValue={1}
  step={0.01} />

<Slider
  orientation="vertical"
  aria-label="Opacity"
  maxValue={1}
  step={0.01} />

<Slider
  orientation="vertical"
  aria-label="Opacity"
  maxValue={1}
  step={0.01} />

Controlled value#

The value prop paired with the onChange event can be used to make a slider controlled. The value must fall between the Slider's minimum and maximum values, which default to 0 and 100 respectively. The onChange event receives the new slider value as a parameter, which can be used to update state.

function Example() {
  let [value, setValue] = React.useState(25);
  return (
    <>
      <Slider
        label="Cookies to buy"
        value={value}
        onChange={setValue} />
      <p>Current value: {value}</p>
    </>
  );
}

function Example() {
  let [value, setValue] = React.useState(25);
  return (
    <>
      <Slider
        label="Cookies to buy"
        value={value}
        onChange={setValue} />
      <p>Current value: {value}</p>
    </>
  );
}

function Example() {
  let [value, setValue] =
    React.useState(25);
  return (
    <>
      <Slider
        label="Cookies to buy"
        value={value}
        onChange={setValue}
      />
      <p>
        Current value:
        {' '}
        {value}
      </p>
    </>
  );
}

Multi thumb sliders specify their values as an array rather than a single number.

function Example() {
  let [value, setValue] = React.useState([25, 75]);
  return (
    <>
      <RangeSlider
        label="Range"
        value={value}
        onChange={setValue} />
      <p>Current value: {value.join(' – ')}</p>
    </>
  );
}

function Example() {
  let [value, setValue] = React.useState([25, 75]);
  return (
    <>
      <RangeSlider
        label="Range"
        value={value}
        onChange={setValue} />
      <p>Current value: {value.join(' – ')}</p>
    </>
  );
}

function Example() {
  let [value, setValue] =
    React.useState([
      25,
      75
    ]);
  return (
    <>
      <RangeSlider
        label="Range"
        value={value}
        onChange={setValue}
      />
      <p>
        Current value:
        {' '}
        {value.join(
          ' – '
        )}
      </p>
    </>
  );
}

onChangeEnd#

The onChangeEnd prop can be used to handle when a user stops dragging a slider, whereas the onChange prop is called as the user drags.

function Example() {
  let [value, setValue] = React.useState(25);
  return (
    <>
      <Slider
        label="Cookies to buy"
        defaultValue={value}
        onChangeEnd={setValue} />
      <p>Current value: {value}</p>
    </>
  );
}

function Example() {
  let [value, setValue] = React.useState(25);
  return (
    <>
      <Slider
        label="Cookies to buy"
        defaultValue={value}
        onChangeEnd={setValue} />
      <p>Current value: {value}</p>
    </>
  );
}

function Example() {
  let [value, setValue] =
    React.useState(25);
  return (
    <>
      <Slider
        label="Cookies to buy"
        defaultValue={value}
        onChangeEnd={setValue}
      />
      <p>
        Current value:
        {' '}
        {value}
      </p>
    </>
  );
}

Custom value scale#

By default, slider values are precentages between 0 and 100. A different scale can be used by setting the minValue and maxValue props.

<Slider
  label="Cookies to buy"
  minValue={50}
  maxValue={150}
  defaultValue={100} />

<Slider
  label="Cookies to buy"
  minValue={50}
  maxValue={150}
  defaultValue={100} />

<Slider
  label="Cookies to buy"
  minValue={50}
  maxValue={150}
  defaultValue={100} />

Value formatting#

Values are formatted as a percentage by default, but this can be modified by using the formatOptions prop to specify a different format. formatOptions is compatible with the option parameter of Intl.NumberFormat and is applied based on the current locale.

<Slider
  label="Currency"
  formatOptions={{style: 'currency', currency: 'JPY'}}
  defaultValue={60} />

<Slider
  label="Currency"
  formatOptions={{style: 'currency', currency: 'JPY'}}
  defaultValue={60} />

<Slider
  label="Currency"
  formatOptions={{
    style: 'currency',
    currency: 'JPY'
  }}
  defaultValue={60}
/>

Step values#

The step prop can be used to snap the value to certain increments. The steps are calculated starting from the minimum. For example, if minValue={2}, and step={3}, the valid step values would be 2, 5, 8, 11, etc. This example allows increments of 5 between 0 and 100.

<Slider
  label="Amount"
  formatOptions={{style: 'currency', currency: 'USD'}}
  minValue={0}
  maxValue={100}
  step={5} />

<Slider
  label="Amount"
  formatOptions={{style: 'currency', currency: 'USD'}}
  minValue={0}
  maxValue={100}
  step={5} />

<Slider
  label="Amount"
  formatOptions={{
    style: 'currency',
    currency: 'USD'
  }}
  minValue={0}
  maxValue={100}
  step={5}
/>

Disabled#

A slider can be disabled using the isDisabled prop.

<Slider
  label="Cookies to share"
  defaultValue={25}
  isDisabled />

<Slider
  label="Cookies to share"
  defaultValue={25}
  isDisabled />

<Slider
  label="Cookies to share"
  defaultValue={25}
  isDisabled
/>

HTML forms#

useSliderThumb supports the name prop for integration with HTML forms.

<Slider
  label="Opacity"
  defaultValue={50}
  name="opacity" />

<Slider
  label="Opacity"
  defaultValue={50}
  name="opacity" />

<Slider
  label="Opacity"
  defaultValue={50}
  name="opacity" />

Internationalization#

Value formatting#

Formatting the value that should be displayed in the value label or aria-valuetext is handled by useSliderState. The formatting can be controlled using the formatOptions prop. If you want to change locales, the I18nProvider must be somewhere in the hierarchy above the Slider. This will tell the formatter what locale to use.

RTL#

In right-to-left languages, the slider should be mirrored. The label is right-aligned, the value is left-aligned. Ensure that your CSS accounts for this.
