## Usage
```tsx
import {
Carousel,
CarouselContent,
CarouselItem,
CarouselNext,
CarouselPrevious,
} from "@/components/ui/carousel"
```
```tsx
<Carousel>
<CarouselContent>
<CarouselItem>...</CarouselItem>
<CarouselItem>...</CarouselItem>
<CarouselItem>...</CarouselItem>
</CarouselContent>
<CarouselPrevious />
<CarouselNext />
</Carousel>
```
## Examples
### Sizes
To set the size of the items, you can use the `basis` utility class on the `<CarouselItem />`.
<ComponentPreview
name="carousel-size"
title="Carousel"
description="A carousel with 3 active items of equal size."
/>
```tsx title="Example" showLineNumbers {4-6}
// 33% of the carousel width.
<Carousel>
<CarouselContent>
<CarouselItem className="basis-1/3">...</CarouselItem>
<CarouselItem className="basis-1/3">...</CarouselItem>
<CarouselItem className="basis-1/3">...</CarouselItem>
</CarouselContent>
</Carousel>
```
```tsx title="Responsive" showLineNumbers {4-6}
// 50% on small screens and 33% on larger screens.
<Carousel>
<CarouselContent>
<CarouselItem className="md:basis-1/2 lg:basis-1/3">...</CarouselItem>
<CarouselItem className="md:basis-1/2 lg:basis-1/3">...</CarouselItem>
<CarouselItem className="md:basis-1/2 lg:basis-1/3">...</CarouselItem>
</CarouselContent>
</Carousel>
```
### Spacing
To set the spacing between the items, we use a `pl-[VALUE]` utility on the `<CarouselItem />` and a negative `-ml-[VALUE]` on the `<CarouselContent />`.
<Callout className="mt-6">
**Why:** I tried to use the `gap` property or a `grid` layout on the `
<CarouselContent />` but it required a lot of math and mental effort to get the
spacing right. I found `pl-[VALUE]` and `-ml-[VALUE]` utilities much easier to
use.
You can always adjust this in your own project if you need to.
</Callout>
<ComponentPreview
name="carousel-spacing"
title="Carousel"
description="A carousel with 3 items with a spacing of 1rem."
/>
```tsx title="Example" showLineNumbers /-ml-4/ /pl-4/
<Carousel>
<CarouselContent className="-ml-4">
<CarouselItem className="pl-4">...</CarouselItem>
<CarouselItem className="pl-4">...</CarouselItem>
<CarouselItem className="pl-4">...</CarouselItem>
</CarouselContent>
</Carousel>
```
```tsx title="Responsive" showLineNumbers /-ml-2/ /pl-2/ /md:-ml-4/ /md:pl-4/
<Carousel>
<CarouselContent className="-ml-2 md:-ml-4">
<CarouselItem className="pl-2 md:pl-4">...</CarouselItem>
<CarouselItem className="pl-2 md:pl-4">...</CarouselItem>
<CarouselItem className="pl-2 md:pl-4">...</CarouselItem>
</CarouselContent>
</Carousel>
```
### Orientation
Use the `orientation` prop to set the orientation of the carousel.
<ComponentPreview
name="carousel-orientation"
title="Carousel"
description="A vertical carousel."
/>
```tsx showLineNumbers /vertical | horizontal/
<Carousel orientation="vertical | horizontal">
<CarouselContent>
<CarouselItem>...</CarouselItem>
<CarouselItem>...</CarouselItem>
<CarouselItem>...</CarouselItem>
</CarouselContent>
</Carousel>
```
## Options
You can pass options to the carousel using the `opts` prop. See the [Embla Carousel docs](https://www.embla-carousel.com/api/options/) for more information.
```tsx showLineNumbers {2-5}
<Carousel
opts={{
align: "start",
loop: true,
}}
>
<CarouselContent>
<CarouselItem>...</CarouselItem>
<CarouselItem>...</CarouselItem>
<CarouselItem>...</CarouselItem>
</CarouselContent>
</Carousel>
```
## API
Use a state and the `setApi` props to get an instance of the carousel API.
<ComponentPreview
name="carousel-api"
title="Carousel"
description="A carousel with a slide counter."
/>
```tsx showLineNumbers {1,4,22}
import { type CarouselApi } from "@/components/ui/carousel"
export function Example() {
const [api, setApi] = React.useState<CarouselApi>()
const [current, setCurrent] = React.useState(0)
const [count, setCount] = React.useState(0)
React.useEffect(() => {
if (!api) {
return
}
setCount(api.scrollSnapList().length)
setCurrent(api.selectedScrollSnap() + 1)
api.on("select", () => {
setCurrent(api.selectedScrollSnap() + 1)
})
}, [api])
return (
<Carousel setApi={setApi}>
<CarouselContent>
<CarouselItem>...</CarouselItem>
<CarouselItem>...</CarouselItem>
<CarouselItem>...</CarouselItem>
</CarouselContent>
</Carousel>
)
}
```
## Events
You can listen to events using the api instance from `setApi`.
```tsx showLineNumbers {1,4-14,16}
import { type CarouselApi } from "@/components/ui/carousel"
export function Example() {
const [api, setApi] = React.useState<CarouselApi>()
React.useEffect(() => {
if (!api) {
return
}
api.on("select", () => {
// Do something on select.
})
}, [api])
return (
<Carousel setApi={setApi}>
<CarouselContent>
<CarouselItem>...</CarouselItem>
<CarouselItem>...</CarouselItem>
<CarouselItem>...</CarouselItem>
</CarouselContent>
</Carousel>
)
}
```
See the [Embla Carousel docs](https://www.embla-carousel.com/api/events/) for more information on using events.
## Plugins
You can use the `plugins` prop to add plugins to the carousel.
```ts showLineNumbers {1,6-10}
import Autoplay from "embla-carousel-autoplay"
export function Example() {
return (
<Carousel
plugins={[
Autoplay({
delay: 2000,
}),
]}
>
// ...
</Carousel>
)
}
```
<ComponentPreview
name="carousel-plugin"
title="Carousel"
description="A carousel with the autoplay plugin."
/>
See the [Embla Carousel docs](https://www.embla-carousel.com/api/plugins/) for more information on using plugins.
