Parameters

Name	Type	Default	Description
aria-labelledby	string		The id of the element containing a label for the slider.
defaultValue	number \| number[]		The default value. Use when the component is not controlled.
disabled	boolean	false	If `true`, the component is disabled.
disableSwap	boolean	false	If `true`, the active thumb doesn't swap when moving pointer over a thumb while dragging another thumb.
isRtl	boolean	false	If `true` the Slider will be rendered right-to-left (with the lowest value on the right-hand side).
marks	boolean \| Mark[]	false	Marks indicate predetermined values to which the user can move the slider. If `true` the marks are spaced according the value of the `step` prop. If an array, it should contain objects with `value` and an optional `label` keys.
max	number	100	The maximum allowed value of the slider. Should not be equal to min.
min	number	0	The minimum allowed value of the slider. Should not be equal to max.
name	string		Name attribute of the hidden `input` element.
onChange	(event: Event, value: number \| number[], activeThumb: number) => void		Callback function that is fired when the slider's value changed.
onChangeCommitted	(event: React.SyntheticEvent \| Event, value: number \| number[]) => void		Callback function that is fired when the `mouseup` is triggered.
orientation	'horizontal' \| 'vertical'	'horizontal'	The component orientation.
rootRef	React.Ref<Element>		The ref attached to the root of the Slider.
scale	(value: number) => number	function Identity(x) { return x; }	A transformation function, to change the scale of the slider.
step	number \| null	1	The granularity with which the slider can step through values. (A "discrete" slider.) The `min` prop serves as the origin for the valid values. We recommend (max - min) to be evenly divisible by the step. When step is `null`, the thumb can only be slid onto marks provided with the `marks` prop.
tabIndex	number		Tab index attribute of the hidden `input` element.
value	number \| number[]		The value of the slider. For ranged sliders, provide an array with two values.

Return value

Name	Type	Description
active	number	The active index of the slider.
axis	Axis	The orientation of the slider.
axisProps	{ [key in Axis]: AxisProps<key> }	Returns the `offset` and `leap` methods to calculate the positioning styles based on the slider axis.
dragging	boolean	If `true`, the slider is being dragged.
focusedThumbIndex	number	The index of the thumb which is focused on the slider.
getHiddenInputProps	<ExternalProps extends Record<string, unknown> = {}>(externalProps?: ExternalProps) => UseSliderHiddenInputProps<ExternalProps>	Resolver for the hidden input slot's props.

getThumbStyle	(index: number) => object	Resolver for the thumb slot's style prop.
marks	Mark[]	The marks of the slider. Marks indicate predetermined values to which the user can move the slider.
open	number	The thumb index for the current value when in hover state.
range	boolean	If `true`, the slider is a range slider when the `value` prop passed is an array.
rootRef	React.RefCallback<Element> \| null	Ref to the root slot's DOM node.
trackLeap	number	The track leap for the current value of the slider.
trackOffset	number	The track offset for the current value of the slider.
