# Install and place "menubar-005" (Collapsing Menubar) from VibeUI

## 1. Install first — do not skip, do not recreate
Run this exact command before writing any code:
npx shadcn@latest add https://vibeui.ru/r/menubar-005.json

Registry item: https://vibeui.ru/r/menubar-005.json
Installs to: components/vibeui/menubar-005.tsx (the exact path follows this project's components.json aliases).
npm dependencies: none.
Registry dependencies: none.

Install it from the registry. Do not recreate it from the description,
do not substitute a similar component from another library, and do not
rewrite it to match the project's existing style.

## 2. What it is
A menubar that folds into a burger on narrow widths: the threshold comes from the block's own width, not the window size.

A menubar with two faces: a wide row of sections and a burger when space runs out. A container query does the switching, so the component behaves the same on a phone and in a narrow desktop column. Zero dependencies, one file, no client JS.

## 3. How to use it
import { Menubar005 } from "@/components/vibeui/menubar-005"

<Menubar005
  burgerLabel="Menu"
  menus={[{ label: "File", items: ["New project", "Open…"] }]}
/>

Read the installed file for the full prop list.

## 4. Where to place it
This is a small inline component. Put it exactly where the user asked,
inside the existing markup. Do not create a new page, section or
wrapper for it. If a similar control already sits in that spot,
replace it instead of adding a second one.

Placement: ___
(The user fills this line in. If it is still blank, ask where to put it
instead of guessing.)

## 5. Keep exactly as installed
- the local --vibeui-menubar-005-* palette — do not swap it for your theme tokens (bg-background, border-border and the like)
- the container query instead of a media query: the component must react to its own width, or a narrow column keeps the wide row
- the layout rule on the inner [data-part="shell"] rather than the root: @container does not apply to the container itself
- display:none on the hidden face: a row hidden with opacity stays in the tab order and in the accessibility tree
- the shared name attribute on the wide view's <details> — it is how sections close one another
- the section headings inside the burger: without them the list becomes two dozen identical rows

## 6. You may change
- the menus array: sections and their items
- burgerLabel — the collapsed button's caption
- the switching threshold in the container query
- the accent through the accent prop — it colours the focus ring

## 7. Rules
- Both faces live in the markup, so the items are listed twice: with a very long menu that shows up in page weight.
- Escape does not close a <details>: that is the element's behaviour, not a bug.
- The 30rem threshold is tuned to the sample labels: longer names need a larger threshold.
- Do not lift the CSS variables into globals.css: the component has to stay a single file.

## 8. Verify
- it renders with no console errors;
- it looks like the preview on the VibeUI page you copied this from;
- if it does not, you changed something listed in section 5 — put it back.

For developers

npx shadcn@latest add https://vibeui.ru/r/menubar-005.json
https://vibeui.ru/r/menubar-005.json

Компонент самодостаточен: один файл, без зависимостей, собственная палитра в локальных переменных --vibeui-menubar-005-*. Серверный: хуков нет, состояние держат <details>. Широкий и узкий виды лежат в разметке одновременно, лишний убирается display:none — так он не попадает ни в порядок табуляции, ни в дерево доступности. Порог переключения задан контейнерным запросом на внутреннем [data-part="shell"], потому что правило внутри @container не действует на сам контейнер. Разделы в широком виде закрывают друг друга через общий атрибут name.

Component source

The same file your agent installs. Here in case you would rather copy it by hand.

import type { CSSProperties } from "react"

export type Menubar005Menu = {
  label: string
  items: string[]
}

export type Menubar005Props = {
  menus?: Menubar005Menu[]
  burgerLabel?: string
  accent?: string
  className?: string
  style?: CSSProperties
}

// Идея компонента: строка меню, которая на узкой ширине сворачивается в одну
// кнопку-бургер. Порог считается от собственной ширины блока (@container), а не
// от окна: тот же компонент в узкой колонке ведёт себя как на телефоне. Оба вида
// живут в разметке одновременно, и лишний убирается display:none — так он не
// попадает ни в порядок табуляции, ни в дерево доступности.
