# Install and place "breadcrumb-004" (Expandable Crumbs) 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/breadcrumb-004.json

Registry item: https://vibeui.ru/r/breadcrumb-004.json
Installs to: components/vibeui/breadcrumb-004.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
The collapsed middle opens as a list on a native details: hidden levels stay reachable instead of merely hidden.

Breadcrumbs with a collapsed middle that expands into a list: native details, zero client code, hidden levels clickable. Zero dependencies, one file.

## 3. How to use it
import { Breadcrumb004 } from "@/components/vibeui/breadcrumb-004"

<Breadcrumb004 items={items} visible={2} />

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-breadcrumb-004-* palette — do not swap it for your theme tokens
- details/summary instead of a stateful button: expansion and keyboard support come free
- the aria-label on the ellipsis naming how many levels are hidden
- keeping hidden levels reachable: an ellipsis with nothing behind it is a dead end
- the first level and the tail visible: "where from" and "where am I" must not hide
- the z-index on the popup list — otherwise it slides under neighbouring content

## 6. You may change
- the items array and the visible count
- the accent through the accent prop
- the popup width
- a different glyph in place of the ellipsis

## 7. Rules
- The list opens downward and can overflow a narrow container: check it on a phone.
- Collapsing two levels is pointless: it pays off from four upward.
- details closes on its summary but not on an outside click: that needs JS, and skipping it is a deliberate trade.
- 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/breadcrumb-004.json
https://vibeui.ru/r/breadcrumb-004.json

Компонент самодостаточен: один файл, без зависимостей, собственная палитра в локальных переменных --vibeui-breadcrumb-004-*. Серверный компонент: раскрытие держит нативный <details>, useId нужен только для имени группы. Многоточие — это <summary> с aria-label, называющим число скрытых уровней. Список скрытых крошек позиционируется абсолютно под многоточием.

Component source

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

import { useId } from "react"
import type { ComponentPropsWithoutRef, CSSProperties } from "react"

export type Breadcrumb004Item = {
  label: string
  href?: string
}

export type Breadcrumb004Props = Omit<
  ComponentPropsWithoutRef<"nav">,
  "children"
> & {
  items?: Breadcrumb004Item[]
  visible?: number
  accent?: string
}

// Идея компонента: свёрнутая середина раскрывается списком, а не исчезает.
// Многоточие здесь — <summary> нативного <details>: раскрытие без единой
// строки клиентского кода, с клавиатуры и с правильной ролью. Скрытые уровни
// остаются достижимы, а не просто спрятаны за троеточием.
