Are the ai2 Motion toggle groups 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.

Motion toggle groups

Five single-select toggle groups that share one idea: the active indicator travels between options instead of jumping. Only the transition character changes, from a soft slide to a bouncy spring or a morphing underline. Each is self-contained, sized, token-driven, and every button is a real button with aria-pressed.

Installation

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

Run the following command

npx shadcn@latest add @ai2/toggle-group-motion

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

Install dependencies

npm install motion lucide-react

Copy the source

components/ui/toggle-group-motion.tsx

"use client"

import * as React from "react"
import { AlignCenter, AlignLeft, AlignRight } from "lucide-react"
import { motion, useReducedMotion } from "motion/react"

/* Motion toggle group family: 5 decorative single-select controls. The shared idea
   is carrying the ACTIVE INDICATOR between options with animation: because the
   indicator is shared through a framer `layoutId` it slides to the new option rather
   than jumping. The variants only change the transition character of the indicator
   (a soft slide, pop, dissolve, a springy hop, a morphing bar). Every button is a
   real <button> + aria-pressed + a focus-visible ring. Color comes ONLY from
   semantic tokens; alpha via color-mix. While useReducedMotion is on the indicator
   moves instantly. The layoutId is unique per instance via React.useId(), so groups
   on the same page do not leak animation into each other. */

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.

Slide

A soft spring slides the indicator to the new segment.

Pop

The indicator scales up as it lands on the option.

Fade

The tinted indicator dissolves across on an eased tween.

Spring

A bouncy spring lets the pill overshoot and settle.

Morph

A thin underline bar travels beneath the active option.

ai2 Motion toggle groups: 5 styled variations on the token system

The ai2 Motion toggle groups are a set of 5 decorative button variations from the styled layer of the @ai2 design system, built around toggle groups whose active indicator animates between options. 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 shares a layoutId, so the indicator moves to the newly selected option. The styled layer is opt-in, so the dependency only lands if you use it; the base components stay lean. Under reduced motion, the indicator changes position instantly with no animation.

What is in the ai2 Motion toggle groups?

5 exports in one file: Slide, Pop, Fade, Spring and Morph. 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 shares a layoutId, so the indicator moves to the newly selected option.
Reduced-motion aware: Under prefers-reduced-motion, the indicator changes position instantly with no animation.
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 Motion toggle groups 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.
