Slider

Allows users to select a value from a continuous range by sliding a handle.

	<script lang="ts">
  import { Slider } from "bits-ui";
  import { cn } from "$lib/utils/styles.js";
 
  let value = [20, 80];
</script>
 
<div class="w-full md:max-w-[280px]">
  <Slider.Root
    bind:value
    class="relative flex w-full touch-none select-none items-center"
  >
    {#snippet children({ thumbs, ticks })}
      <span
        class="relative h-2 w-full grow overflow-hidden rounded-full bg-dark-10"
      >
        <Slider.Range class="absolute h-full bg-foreground" />
      </span>
      {#each thumbs as index}
        <Slider.Thumb
          {index}
          class={cn(
            "block size-[25px] cursor-pointer rounded-full border border-border-input bg-background shadow transition-colors hover:border-dark-40 focus-visible:outline-none focus-visible:ring-2 focus-visible:ring-foreground focus-visible:ring-offset-2 active:scale-98 disabled:pointer-events-none disabled:opacity-50 dark:shadow-card",
            index === 0 ? "bg-blue-400" : "bg-yellow-300"
          )}
        />
      {/each}
      {#each ticks as index}
        <Slider.Tick {index} class="block h-1 w-1 rounded-full bg-dark-10" />
      {/each}
    {/snippet}
  </Slider.Root>
</div>

Structure

	<script lang="ts">
	import { Slider } from "bits-ui";
</script>
 
<Slider.Root>
	<Slider.Range />
	<Slider.Thumb />
	<Slider.Input />
</Slider.Root>

Examples

Multiple Thumbs and Ticks

If the value prop has more than one value, the slider will render multiple thumbs. You can also use the ticks slot prop to render ticks at specific intervals.

	<script lang="ts">
	import { Slider } from "bits-ui";
 
	let value = [5, 7];
</script>
 
<Slider.Root min={0} max={10} step={1} bind:value let:ticks let:thumbs>
	<Slider.Range />
 
	{#each thumbs as thumb}
		<Slider.Thumb {thumb} />
	{/each}
 
	{#each ticks as tick}
		<Slider.Tick {tick} />
	{/each}
</Slider.Root>

Vertical Orientation

You can use the orientation prop to change the orientation of the slider, which defaults to "horizontal".

	<Slider.Root let:thumbs orientation="vertical">
	<Slider.Range />
 
	{#each thumbs as thumb}
		<Slider.Thumb {thumb} />
	{/each}
</Slider.Root>

RTL Support

You can use the dir prop to change the reading direction of the slider, which defaults to "ltr".

	<Slider.Root let:thumbs dir="rtl">
	<Slider.Range />
 
	{#each thumbs as thumb}
		<Slider.Thumb {thumb} />
	{/each}
</Slider.Root>
