Props

Props of the SliderUnstyled component are also available.

Name	Type	Default	Description
aria-label	string		The label of the slider.
aria-labelledby	string		The id of the element containing a label for the slider.
aria-valuetext	string		A string value that provides a user-friendly name for the current value of the slider.
classes	object		Override or extend the styles applied to the component. See CSS API below for more details.
color	'primary' \| 'secondary' \| string	'primary'	The color of the component. It supports those theme colors that make sense for this component.
component	elementType		The component used for the root node. Either a string to use a HTML element or a component.
components	{ Mark?: elementType, MarkLabel?: elementType, Rail?: elementType, Root?: elementType, Thumb?: elementType, Track?: elementType, ValueLabel?: elementType }	{}	The components used for each slot inside the Slider. Either a string to use a HTML element or a component.
componentsProps	object	{}	The props used for each slot inside the Slider.
defaultValue	Array<number> \| number		The default value. Use when the component is not controlled.
disabled	bool	false	If `true`, the component is disabled.
disableSwap	bool	false	If `true`, the active thumb doesn't swap when moving pointer over a thumb while dragging another thumb.
getAriaLabel	func		Accepts a function which returns a string value that provides a user-friendly name for the thumb labels of the slider. This is important for screen reader users. Signature: `function(index: number) => string` index: The thumb label's index to format.
getAriaValueText	func		Accepts a function which returns a string value that provides a user-friendly name for the current value of the slider. This is important for screen reader users. Signature: `function(value: number, index: number) => string` value: The thumb label's value to format. index: The thumb label's index to format.
isRtl	bool	false	Indicates whether the theme context has rtl direction. It is set automatically.
marks	Array<{ label?: node, value: number }> \| bool	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	func		Callback function that is fired when the slider's value changed. Signature: `function(event: Event, value: number \| Array<number>, activeThumb: number) => void` event: The event source of the callback. You can pull out the new value by accessing `event.target.value` (any). Warning: This is a generic event not a change event. value: The new value. activeThumb: Index of the currently moved thumb.
onChangeCommitted	func		Callback function that is fired when the `mouseup` is triggered. Signature: `function(event: React.SyntheticEvent \| Event, value: number \| Array<number>) => void` event: The event source of the callback. Warning: This is a generic event not a change event. value: The new value.
orientation	'horizontal' \| 'vertical'	'horizontal'	The component orientation.
scale	func	(x) => x	A transformation function, to change the scale of the slider.
size	'small' \| 'medium'	'medium'	The size of the slider.
step	number	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.
sx	func \| object		The system prop that allows defining system overrides as well as additional CSS styles. See the `sx` page for more details.
tabIndex	number		Tab index attribute of the hidden `input` element.
track	'inverted' \| 'normal' \| false	'normal'	The track presentation: - `normal` the track will render a bar representing the slider value. - `inverted` the track will render a bar representing the remaining slider value. - `false` the track will render without a bar.
value	Array<number> \| number		The value of the slider. For ranged sliders, provide an array with two values.
valueLabelDisplay	'auto' \| 'off' \| 'on'	'off'	Controls when the value label is displayed: - `auto` the value label will display when the thumb is hovered or focused. - `on` will display persistently. - `off` will never display.
valueLabelFormat	func \| string	(x) => x	The format function the value label's value. When a function is provided, it should have the following signature: - {number} value The value label's value to format - {number} index The value label's index to format

The ref is forwarded to the root element.
