Usage
import {
Carousel,
CarouselContent,
CarouselItem,
CarouselNext,
CarouselPrevious,
} from "@/components/ui/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 />
.
// 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>
// 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 />
.
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.
<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>
Orientation
Use the orientation
prop to set the orientation of the 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>
API
Use a state and the setApi
props to get an instance of the carousel API.
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>
)
}
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>
)
}
See the Embla Carousel docs for more information on using plugins.
