API Reference

Root

Contains all the parts of a slider. It will render an input for each thumb when used within a form to ensure events propagate correctly.

Prop	Default	Type
as	'div'	AsTag | Component The element or component this component should render as. Can be overwrite by asChild
asChild		boolean Change the default rendered element for the one passed as a child, merging their props and behavior. Read our Composition guide for more details.
defaultValue	[0]	number[] The value of the slider when initially rendered. Use when you do not need to control the state of the slider.
dir		'ltr' | 'rtl' The reading direction of the combobox when applicable. If omitted, inherits globally from DirectionProvider or assumes LTR (left-to-right) reading mode.
disabled	false	boolean When true, prevents the user from interacting with the slider.
inverted	false	boolean Whether the slider is visually inverted.
max	100	number The maximum value for the range.
min	0	number The minimum value for the range.
minStepsBetweenThumbs	0	number The minimum permitted steps between multiple thumbs.
modelValue		number[] The controlled value of the slider. Can be bind as v-model.
name		string
orientation	'horizontal'	'vertical' | 'horizontal' The orientation of the slider.
step	1	number The stepping interval.

Emit	Payload
update:modelValue	[payload: number[]] Event handler called when the slider value changes
valueCommit	[payload: number[]] Event handler called when the value changes at the end of an interaction. Useful when you only need to capture a final value e.g. to update a backend service.

Slots (default)	Payload
modelValue	number[] Current slider values

Data Attribute	Value
[data-disabled]	Present when disabled
[data-orientation]	"vertical" | "horizontal"

Track

The track that contains the SliderRange.

Prop	Default	Type
as	'span'	AsTag | Component The element or component this component should render as. Can be overwrite by asChild
asChild		boolean Change the default rendered element for the one passed as a child, merging their props and behavior. Read our Composition guide for more details.

Data Attribute	Value
[data-disabled]	Present when disabled
[data-orientation]	"vertical" | "horizontal"

Range

The range part. Must live inside SliderTrack.

Prop	Default	Type
as	'span'	AsTag | Component The element or component this component should render as. Can be overwrite by asChild
asChild		boolean Change the default rendered element for the one passed as a child, merging their props and behavior. Read our Composition guide for more details.

Data Attribute	Value
[data-disabled]	Present when disabled
[data-orientation]	"vertical" | "horizontal"

Thumb

A draggable thumb. You can render multiple thumbs.

Prop	Default	Type
as	'div'	AsTag | Component The element or component this component should render as. Can be overwrite by asChild
asChild		boolean Change the default rendered element for the one passed as a child, merging their props and behavior. Read our Composition guide for more details.

Data Attribute	Value
[data-disabled]	Present when disabled
[data-orientation]	"vertical" | "horizontal"

Examples

Vertical orientation

Use the orientation prop to create a vertical slider.

// index.vue
<script setup>
import { SliderRange, SliderRoot, SliderThumb, SliderTrack } from 'radix-vue'
</script>

<template>
  <SliderRoot class="SliderRoot" :default-value="[50]" orientation="vertical">
    <SliderTrack class="SliderTrack">
      <SliderRange class="SliderRange" />
    </SliderTrack>
    <SliderThumb class="SliderThumb" />
  </SliderRoot>
</template>

/* styles.css */
.SliderRoot {
  position: relative;
  display: flex;
  align-items: center;
}
.SliderRoot[data-orientation="vertical"] {
  flex-direction: column;
  width: 20px;
  height: 100px;
}

.SliderTrack {
  position: relative;
  flex-grow: 1;
  background-color: grey;
}
.SliderTrack[data-orientation="vertical"] {
  width: 3px;
}

.SliderRange {
  position: absolute;
  background-color: black;
}
.SliderRange[data-orientation="vertical"] {
  width: 100%;
}

.SliderThumb {
  display: block;
  width: 20px;
  height: 20px;
  background-color: black;
}

Create a range

Add multiple thumbs and values to create a range slider.

// index.vue
<script setup>
import { SliderRange, SliderRoot, SliderThumb, SliderTrack } from 'radix-vue'
</script>

<template>
  <SliderRoot :default-value="[25, 75]">
    <SliderTrack>
      <SliderRange />
    </SliderTrack>
    <SliderThumb />
    <SliderThumb />
  </SliderRoot>
</template>

Define step size

Use the step prop to increase the stepping interval.

// index.vue
<script setup>
import { SliderRange, SliderRoot, SliderThumb, SliderTrack } from 'radix-vue'
</script>

<template>
  <SliderRoot :default-value="[50]" :step="10">
    <SliderTrack>
      <SliderRange />
    </SliderTrack>
    <SliderThumb />
  </SliderRoot>
</template>

Prevent thumb overlap

Use minStepsBetweenThumbs to avoid thumbs with equal values.

// index.vue
<script setup>
import { SliderRange, SliderRoot, SliderThumb, SliderTrack } from 'radix-vue'
</script>

<template>
  <SliderRoot
    :default-value="[25, 75]"
    :step="10"
    :min-steps-between-thumbs="1"
  >
    <SliderTrack>
      <SliderRange />
    </SliderTrack>
    <SliderThumb />
    <SliderThumb />
  </SliderRoot>
</template>

Accessibility

Adheres to the Slider WAI-ARIA design pattern.

Keyboard Interactions

Key	Description
ArrowRight	Increments/decrements by the step value depending on orientation.
ArrowLeft	Increments/decrements by the step value depending on orientation.
ArrowUp	Increases the value by the step amount.
ArrowDown	Decreases the value by the step amount.
PageUp	Increases the value by a larger step.
PageDown	Decreases the value by a larger step.
Shift + ArrowUp	Increases the value by a larger step.
Shift + ArrowDown	Decreases the value by a larger step.
Home	Sets the value to its minimum.
End	Sets the value to its maximum.

Custom APIs

Create your own API by abstracting the primitive parts into your own component.

Abstract all parts

This example abstracts all of the Slider parts so it can be used as a self closing element.

Usage

<script setup lang="ts">
import { Slider } from './your-slider'
</script>

<template>
  <Slider :default-value="[25]" />
</template>

Implementation

// your-slider.ts
export { default as Slider } from 'Slider.vue'

 <!-- Slider.vue -->
<script setup lang="ts">
import { SlideRoot, SliderRange, type SliderRootEmits, type SliderRootProps, SliderThumb, SliderTrack, useForwardPropsEmits } from 'radix-vue'

const props = defineProps<SliderRootProps>()
const emits = defineEmits<SliderRootEmits>()

const forward = useForwardPropsEmits(props, emits)
</script>

<template>
  <SliderRoot v-bind="forward">
    <SliderTrack>
      <SliderRange />
    </SliderTrack>

    <SliderThumb v-for="(_, i) in value" :key="i" />
  </SliderRoot>
</template>

Caveats

Mouse events are not fired

Because of a limitation we faced during implementation, the following example won't work as expected and the @mousedown and @mousedown event handlers won't be fired:

<SliderRoot
  @mousedown="() => { console.log('onMouseDown')  }"
  @mouseup="() => { console.log('onMouseUp')  }"
>
  …
</SliderRoot>

We recommend using pointer events instead (eg. @pointerdown, @pointerup). Regardless of the above limitation, these events are better suited for cross-platform/device handling as they are fired for all pointer input types (mouse, touch, pen, etc.).
