About

The carousel component is built using the Embla Carousel library.

Installation

Usage

import {
  Carousel,
  CarouselContent,
  CarouselItem,
  CarouselNext,
  CarouselPrevious,
} from "@/components/ui/carousel"

import {
  Carousel,
  CarouselContent,
  CarouselItem,
  CarouselNext,
  CarouselPrevious,
} from "@/components/ui/carousel"

<Carousel>
  <CarouselContent>
    <CarouselItem>...</CarouselItem>
    <CarouselItem>...</CarouselItem>
    <CarouselItem>...</CarouselItem>
  </CarouselContent>
  <CarouselPrevious />
  <CarouselNext />
</Carousel>

<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 />.

Preview
Code

<Carousel>
  <CarouselContent className="-ml-4">
    <CarouselItem className="pl-4">...</CarouselItem>
    <CarouselItem className="pl-4">...</CarouselItem>
    <CarouselItem className="pl-4">...</CarouselItem>
  </CarouselContent>
</Carousel>

<Carousel>
  <CarouselContent className="-ml-4">
    <CarouselItem className="pl-4">...</CarouselItem>
    <CarouselItem className="pl-4">...</CarouselItem>
    <CarouselItem className="pl-4">...</CarouselItem>
  </CarouselContent>
</Carousel>

<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>

<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>

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 />.

Why: I have been using 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.

    <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.

Preview
Code

<Carousel orientation="vertical | horizontal">
  <CarouselContent>
    <CarouselItem>...</CarouselItem>
    <CarouselItem>...</CarouselItem>
    <CarouselItem>...</CarouselItem>
  </CarouselContent>
</Carousel>

<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 for more information.

<Carousel
  opts={{
    align: "start",
    loop: true,
  }}
>
  <CarouselContent>
    <CarouselItem>...</CarouselItem>
    <CarouselItem>...</CarouselItem>
    <CarouselItem>...</CarouselItem>
  </CarouselContent>
</Carousel>

<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.

Code

Slide 0 of 0

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>
  )
}

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.

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>
  )
}

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 for more information on using events.

Plugins

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

import Autoplay from "embla-carousel-autoplay"
 
export function Example() {
  return (
    <Carousel
      plugins={[
        Autoplay({
          delay: 2000,
        }),
      ]}
    >
      // ...
    </Carousel>
  )
}

import Autoplay from "embla-carousel-autoplay"
 
export function Example() {
  return (
    <Carousel
      plugins={[
        Autoplay({
          delay: 2000,
        }),
      ]}
    >
      // ...
    </Carousel>
  )
}
