Usage
usage.tsx
import { Carousel, CarouselContent, CarouselItem, CarouselNext, CarouselPrevious } from "@/components/ui/8bit/carousel";export function CarouselExamples() { return ( <> <Carousel className="mx-auto max-w-md"> <CarouselContent> <CarouselItem><div className="p-6">Featured item</div></CarouselItem> <CarouselItem><div className="p-6">Another item</div></CarouselItem> <CarouselItem><div className="p-6">A third item</div></CarouselItem> </CarouselContent> <CarouselPrevious /> <CarouselNext /> </Carousel> <Carousel orientation="vertical" className="mx-auto max-w-md"> <CarouselContent> <CarouselItem><div className="p-6">First update</div></CarouselItem> <CarouselItem><div className="p-6">Second update</div></CarouselItem> </CarouselContent> <CarouselPrevious aria-label="Previous update" /> <CarouselNext aria-label="Next update" /> </Carousel> </> );}- Present a browsable sequence of cards, images, or other slide content when showing everything at once would take too much space.
- Use horizontal orientation for standard left-to-right galleries or vertical orientation for stacked, vertically navigable slides.
- Add the built-in previous and next buttons when users need visible carousel controls.
- Use the exposed Embla API when application logic needs to control or observe carousel behavior.
Examples
Horizontal card carousel
Show a row of full-width cards with the built-in navigation controls.
horizontal-card-carousel.tsx
import { Carousel, CarouselContent, CarouselItem, CarouselNext, CarouselPrevious } from "@/components/ui/8bit/carousel";export function FeaturedCards() { return ( <Carousel className="mx-auto max-w-lg"> <CarouselContent> <CarouselItem><article className="p-6">New releases</article></CarouselItem> <CarouselItem><article className="p-6">Popular picks</article></CarouselItem> <CarouselItem><article className="p-6">Staff favorites</article></CarouselItem> </CarouselContent> <CarouselPrevious /> <CarouselNext /> </Carousel> );}Vertical updates carousel
Stack slides vertically and provide descriptive labels for the navigation controls.
vertical-updates-carousel.tsx
import { Carousel, CarouselContent, CarouselItem, CarouselNext, CarouselPrevious } from "@/components/ui/8bit/carousel";export function UpdatesCarousel() { return ( <Carousel orientation="vertical" className="mx-auto max-w-md"> <CarouselContent> <CarouselItem><article className="p-6">Version 1.2 released</article></CarouselItem> <CarouselItem><article className="p-6">New features added</article></CarouselItem> </CarouselContent> <CarouselPrevious aria-label="Previous update" /> <CarouselNext aria-label="Next update" /> </Carousel> );}API reference
PropTypeDefaultDescription
optsCarouselOptions (Embla options)—Optional options passed to `useEmblaCarousel`. The component sets Embla's `axis` from `orientation`, overriding any `axis` value in `opts`.
pluginsCarouselPlugin (Embla plugins)—Optional plugin or plugins passed as the second argument to `useEmblaCarousel`.
orientation"horizontal" | "vertical""horizontal"Sets the carousel axis and the layout direction and positioning of its slides and navigation controls.
setApi(api: CarouselApi) => void—Optional callback invoked by an effect when the Embla API is available. `CarouselApi` is exported from this module.
HTML div attributesReact.HTMLAttributes<HTMLDivElement>—`Carousel` accepts standard div attributes, including `className`, `children`, and event handlers. `CarouselContent` and `CarouselItem` also accept standard div attributes.
CarouselPrevious and CarouselNext propsReact.ComponentProps<typeof Button>—Both controls accept the 8bit Button component's props. Their `variant` defaults to `"outline"` and `size` defaults to `"icon"`; each also sets its own `disabled` state and click handler.
Accessibility
- The root element has `role="region"` and `aria-roledescription="carousel"`.
- Each `CarouselItem` has `role="group"` and `aria-roledescription="slide"`; the component does not add slide position or title labels.
- Previous and next controls include screen-reader-only text (“Previous slide” and “Next slide”) and are disabled when scrolling in their direction is unavailable.
- The root handles Left and Right Arrow keys during captured keydown events. This behavior is also used in vertical orientation.
- Give slide content meaningful accessible names and consider adding labels to the carousel region and slides where needed. Custom control children or labels should remain understandable to assistive technology.
