Are the ai2 Tone menubars 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 menubars

Five menubars that keep one skeleton and vary only the semantic tone: info, success, warning, danger and a neutral muted. Each reads its own token family for the soft bar surface, the solid open menu, the panel border and the item hover. Self-contained (no radix), sized, token-driven, and closes on outside click or Escape.

MenubarTone

Installation

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

Run the following command

npx shadcn@latest add @ai2/menubar-tone

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

Install dependencies

npm install motion lucide-react

Copy the source

components/ui/menubar-tone.tsx

"use client"

import * as React from "react"
import { AlertTriangle, CheckCircle2, Info, Minus, OctagonAlert } from "lucide-react"
import { AnimatePresence, motion, useReducedMotion } from "motion/react"

import { cn } from "@/lib/utils"

/* Tone menubar family: 5 decorative, SELF-SUFFICIENT menubars. NO radix or portal.
   The skeleton is the same in every variant; the whole difference is the SEMANTIC
   TONE family: info, success, warning, danger and the neutral muted. Each variant
   uses its own token family (<tone>, <tone>-foreground, <tone>-soft,
   <tone>-soft-foreground): a soft tone surface for the bar, a filled tone for the
   open menu, a tone border for the panel and tone-soft for item hover. Classic
   menubar behavior: while one menu is open, hovering a sibling trigger switches to
   that menu. It closes on an outside click, on Escape (focus returns to the
   trigger) and on an item selection. Left/Right arrows move between the top-level
   menus and Up/Down moves inside the open one. No transform under reduced motion.
   Color comes ONLY from tokens, via alpha color-mix. */

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 info token family across bar, menu and items.

Success

The success token family for confirming flows.

Warning

The warning token family for cautious actions.

Danger

The danger token family for destructive menus.

Muted

A neutral menubar on the muted token family.

ai2 Tone menubars: 5 styled variations on the token system

The ai2 Tone menubars are a set of 5 decorative button variations from the styled layer of the @ai2 design system, built around application menu bars driven by the semantic tone tokens. 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 springs the open dropdown in and out. The styled layer is opt-in, so the dependency only lands if you use it; the base components stay lean. Under reduced motion, the transforms are skipped and the menu fades in place.

What is in the ai2 Tone menubars?

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 springs the open dropdown in and out.
Reduced-motion aware: Under prefers-reduced-motion, the transforms are skipped and the menu fades in place.
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 menubars 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.
