Are the ai2 Tone 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.

Tone toggle groups

Five single-select toggle groups that share one structure and vary only in meaning: each is painted with a single semantic tone, so the active option carries that tone's fill and its matching foreground while the rest stay neutral. Each root carries data-tone, is self-contained, sized, and token-driven.

Installation

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

Run the following command

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

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

Install dependencies

npm install motion lucide-react

/* Tone toggle group family: 5 decorative single-select controls. The shared idea is
   the SEMANTIC TONE: each variant is painted with a single meaning color (info,
   success, warning, danger, muted); the active option carries that tone's fill and
   the inactive ones carry neutral text. The structure is the same in every variant,
   so the only difference is color. The root carries `data-tone`.
   Color comes ONLY from semantic tokens; alpha via color-mix. The active indicator
   slides with a framer layoutId and moves instantly while useReducedMotion is on;
   the layoutId is unique per instance via React.useId(). */

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.

Info

The informative tone for a neutral run of choices.

Success

The positive tone, marking a confirmed selection.

Warning

The caution tone for a risky run of choices.

Danger

The destructive tone for selections you cannot undo.

Muted

The colourless tone for choices that should stay quiet.

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

The ai2 Tone toggle groups are a set of 5 decorative button variations from the styled layer of the @ai2 design system, built around toggle groups painted with a single semantic tone. 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 slides the filled tone indicator to the active 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 Tone toggle groups?

5 exports in one file: Info, Success, Warning, Danger and Muted. 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 slides the filled tone indicator to the active 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 Tone 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.
