Are the ai2 Thumbnail carousels free?

Yes. The whole styled layer is free and MIT licensed, like the component core.

Can I change the size?

Yes. Every variation takes a size prop of sm, md, lg or xl, aligned to the base Button height scale.

Thumbnail carousels

Five carousels with a thumbnail strip: below, side, dots and thumbs, scaled and bordered. Clicking a thumbnail jumps to that slide while the main viewer cross-fades. Self-contained (no embla), token-driven and sized.

CarouselThumbnails

Installation

The styled layer is free and installs like any other ai2 component.

Run the following command

npx shadcn@latest add @ai2/carousel-thumbnails

Dependencies, the @ai2/tokens theme and the component file are installed together.

Manual installs skip the @ai2/tokens theme, so add the token CSS from the theming guide or the tone colors will be missing.

Variations

5 takes on the same idea. Each is its own export, and every one accepts a size prop (sm, md, lg, xl) aligned to the base Button scale.

Below

A thumbnail row sits under the main viewer; the active thumb takes a primary border.

Side

The thumbnail strip is a vertical column to the right of the viewer.

Dots + Thumbs

Thumbnails below plus a dot indicator.

Scaled

The active thumbnail scales up while the others shrink.

Bordered

Each thumbnail has a bold border; the active one turns primary.

ai2 Thumbnail carousels: 5 styled variations on the token system

The ai2 Thumbnail carousels are a set of 5 decorative button variations from the styled layer of the @ai2 design system, built around carousels with a thumbnail strip where clicking a thumb jumps to that slide. They are free and MIT licensed, and every color comes from a semantic token, so they theme with the rest of ai2 in light and dark.

Motion runs on framer-motion: framer-motion cross-fades the main viewer and springs the active thumbnail. The styled layer is opt-in, so the dependency only lands if you use it; the base components stay lean. Under reduced motion, the main viewer changes instantly and the thumbnails do not scale.

What is in the ai2 Thumbnail carousels?

5 exports in one file: Below, Side, Dots and Thumbs, Scaled and Bordered. Each renders a native button and takes a size prop (sm, md, lg, xl) aligned to the base Button. They are separate from the base Button on purpose: the base keeps its clean variant, tone and size axes, while the styled layer carries the effects.

You own the file. Copy the one category file and you have all 5 variations, with no runtime dependency on ai2 itself.

Why use it

On-system by construction: Every color resolves to an ai2 semantic token, so the buttons follow your theme in light and dark with no extra work.
Effect without the sprawl: The decorations live in a dedicated styled file, so the base Button keeps its clean, predictable API.
Accessible and honest: Each renders a real button element, keeps a visible focus ring, and respects prefers-reduced-motion.

Features

Token-driven color: No hardcoded hex or oklch; the look recolors with your theme tokens.
framer-motion: framer-motion cross-fades the main viewer and springs the active thumbnail.
Reduced-motion aware: Under prefers-reduced-motion, the main viewer changes instantly and the thumbnails do not scale.
Size aligned to the base: Every variation takes sm, md, lg and xl matching the base Button height scale, so styled and base buttons line up in a row.

Production tips

Use it for emphasis, not everywhere: Styled buttons draw the eye. Reserve them for the one action you want people to take on a screen, and use the base Button for the rest.
Keep labels as verbs: The decoration adds weight, so a clear action label keeps the button scannable.
Pick one variation per surface: The variations share a family; using two different ones in the same view competes for attention.

Works with the rest of ai2

The Thumbnail carousels sit alongside the base Button and the rest of the @ai2 registry. They share the same token file, so a styled action next to a base button or a badge stays visually consistent in both modes.
