About

Installation

	npx  shadcn-svelte@latest add carousel

Usage

	<script lang="ts">
  import * as Carousel from "$lib/components/ui/carousel/index.js";
</script>
 
<Carousel.Root>
  <Carousel.Content>
    <Carousel.Item>...</Carousel.Item>
    <Carousel.Item>...</Carousel.Item>
    <Carousel.Item>...</Carousel.Item>
  </Carousel.Content>
  <Carousel.Previous />
  <Carousel.Next />
</Carousel.Root>

Examples

Sizes

To set the size of the items, you can use the basis utility class on the <Carousel.Item />.

Example
	<!-- 33% of the carousel width. -->
<Carousel.Root>
  <Carousel.Content>
    <Carousel.Item class="basis-1/3">...</Carousel.Item>
    <Carousel.Item class="basis-1/3">...</Carousel.Item>
    <Carousel.Item class="basis-1/3">...</Carousel.Item>
  </Carousel.Content>
</Carousel.Root>
Responsive
	<!-- 50% on small screens and 33% on larger screens. -->
<Carousel.Root>
  <Carousel.Content>
    <Carousel.Item class="md:basis-1/2 lg:basis-1/3">...</Carousel.Item>
    <Carousel.Item class="md:basis-1/2 lg:basis-1/3">...</Carousel.Item>
    <Carousel.Item class="md:basis-1/2 lg:basis-1/3">...</Carousel.Item>
  </Carousel.Content>
</Carousel.Root>

Spacing

To set the spacing between the items, we use a pl-[VALUE] utility on the <Carousel.Item /> and a negative -ml-[VALUE] on the <Carousel.Content />.

Example
	<Carousel.Root>
  <Carousel.Content class="-ml-4">
    <Carousel.Item class="pl-4">...</Carousel.Item>
    <Carousel.Item class="pl-4">...</Carousel.Item>
    <Carousel.Item class="pl-4">...</Carousel.Item>
  </Carousel.Content>
</Carousel.Root>
Responsive
	<Carousel.Root>
  <Carousel.Content class="-ml-2 md:-ml-4">
    <Carousel.Item class="pl-2 md:pl-4">...</Carousel.Item>
    <Carousel.Item class="pl-2 md:pl-4">...</Carousel.Item>
    <Carousel.Item class="pl-2 md:pl-4">...</Carousel.Item>
  </Carousel.Content>
</Carousel.Root>

Orientation

Use the orientation prop to set the orientation of the carousel.

	<Carousel.Root orientation="vertical | horizontal">
  <Carousel.Content>
    <Carousel.Item>...</Carousel.Item>
    <Carousel.Item>...</Carousel.Item>
    <Carousel.Item>...</Carousel.Item>
  </Carousel.Content>
</Carousel.Root>

Options

You can pass options to the carousel using the opts prop. See the Embla Carousel docs for more information.

	<Carousel.Root
  opts={{
    align: "start",
    loop: true,
  }}
>
  <Carousel.Content>
    <Carousel.Item>...</Carousel.Item>
    <Carousel.Item>...</Carousel.Item>
    <Carousel.Item>...</Carousel.Item>
  </Carousel.Content>
</Carousel.Root>

API

Use reactive state and the setApi callback to get an instance of the carousel API.

	<script lang="ts">
  import { type CarouselAPI } from "$lib/components/ui/carousel/context.js";
  import * as Carousel from "$lib/components/ui/carousel/index.js";
 
  let api = $state<CarouselAPI>();
  let current = $state(0);
  const count = $derived(api ? api.scrollSnapList().length : 0);
 
  $effect(() => {
    if (api) {
      current = api.selectedScrollSnap() + 1;
      api.on("select", () => {
        current = api!.selectedScrollSnap() + 1;
      });
    }
  });
</script>
 
<Carousel.Root setApi={(emblaApi) => (api = emblaApi)}>
  <Carousel.Content>
    <Carousel.Item>...</Carousel.Item>
    <Carousel.Item>...</Carousel.Item>
    <Carousel.Item>...</Carousel.Item>
  </Carousel.Content>
</Carousel.Root>

Events

You can listen to events using the api instance from bind:api.

	<script lang="ts">
  import { type CarouselAPI } from "$lib/components/ui/carousel/context.js";
  import * as Carousel from "$lib/components/ui/carousel/index.js";
 
  let api = $state<CarouselAPI>();
 
  $effect(() => {
    if (api) {
      api.on("select", () => {
        // do something
      });
    }
  });
</script>
 
<Carousel.Root setApi={(emblaApi) => (api = emblaApi)}>
  <Carousel.Content>
    <Carousel.Item>...</Carousel.Item>
    <Carousel.Item>...</Carousel.Item>
    <Carousel.Item>...</Carousel.Item>
  </Carousel.Content>
</Carousel.Root>

Plugins

You can use the plugins prop to add plugins to the carousel.

	<script lang="ts">
  import Autoplay from "embla-carousel-autoplay";
  import * as Carousel from "$lib/components/ui/carousel/index.js";
</script>
 
<Carousel.Root
  plugins={[
    Autoplay({
      delay: 2000,
    }),
  ]}
>
  <!-- ... -->
</Carousel.Root>

See the Embla Carousel docs for more information on using plugins.
