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>
