Are the ai2 Accent 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.

Accent menubars

Five menubars that keep one menu and vary only how the open top-level trigger is accented: a soft accent surface, a primary glow, a solid fill, an underline and a leading edge strip. Each is self-contained (no radix), sized, token-driven, switches menus on hover once one is open, and closes on outside click or Escape.

MenubarAccent

Installation

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

Run the following command

npx shadcn@latest add @ai2/menubar-accent

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

Install dependencies

npm install motion

Copy the source

components/ui/menubar-accent.tsx

"use client"

import * as React from "react"
import { AnimatePresence, motion, useReducedMotion } from "motion/react"

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

/* Accent menubar family: 5 decorative, SELF-SUFFICIENT menubars. NO radix or
   portal. The menu content and the motion are the same in every variant; the whole
   difference is the highlight technique of the OPEN/ACTIVE top-level menu: a soft
   accent surface, a primary glow, a filled primary, an underline and a left-edge
   strip. 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.

Bar

The open menu takes a soft accent surface.

Glow

A primary halo rings the open trigger.

Fill

The open menu fills solid primary.

Underline

A thick primary rule sits under the open menu.

Edge

A vertical primary strip marks the leading edge.

ai2 Accent menubars: 5 styled variations on the token system

The ai2 Accent menubars are a set of 5 decorative button variations from the styled layer of the @ai2 design system, built around application menu bars that accent the open top-level menu. 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 Accent menubars?

5 exports in one file: Bar, Glow, Fill, Underline and Edge. 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 Accent 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.
