# Install and place "cascader-008" (Details Tree) 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/cascader-008.json

Registry item: https://vibeui.ru/r/cascader-008.json
Installs to: components/vibeui/cascader-008.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 cascader tree built on native details and radios: levels open without JavaScript, and the chosen branch is highlighted all the way up through :has().

A cascading tree on details and radios: opening and picking work without client JS and submit with an ordinary form. One file, zero dependencies, a server component.

## 3. How to use it
import { Cascader008 } from "@/components/vibeui/cascader-008"

<Cascader008 name="destination" heading="Where to file it" />

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-cascader-008-* palette — do not swap it for your theme tokens
- one shared name across every radio: without it the form receives several values instead of one
- the path highlight through :has(input:checked) — with collapsed branches the tick is otherwise invisible
- the leaf value as a full path: a leaf name without its branch is ambiguous on the server
- the heading as a paragraph rather than a legend: a floated legend makes sibling flex children wrap around it
- the panel's own light surface: dark text disappears on the dark catalogue card

## 6. You may change
- the form field name through name
- the panel heading through heading
- the tree and its initially open branches through tree
- the accent colour through accent

## 7. Rules
- details cannot animate its height — the arrow rotation is the only animation here and it is disabled by prefers-reduced-motion.
- Open branches reset on a re-render: that state lives in the DOM, not in props.
- Only a leaf is selectable: allowing a branch to be picked needs a radio next to the summary.
- 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/cascader-008.json
https://vibeui.ru/r/cascader-008.json

Компонент самодостаточен: один файл, без зависимостей, собственная палитра в локальных переменных --vibeui-cascader-008-*. Серверный: хуков нет, раскрытие уровней ведёт нативный details, выбор — radio с общим именем, поэтому дерево уходит обычной формой даже без JavaScript. Правило details:has(input:checked) > summary подсвечивает всю цепочку родителей: при свёрнутых уровнях иначе не видно, где стоит отметка. Заголовок сделан абзацем, а не legend: legend с float ломает поток соседних flex-детей.

Component source

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

import type { CSSProperties, ReactNode } from "react"

export type Cascader008Node = {
  label: string
  open?: boolean
  children?: Cascader008Node[]
}

export type Cascader008Props = {
  name?: string
  heading?: string
  tree?: Cascader008Node[]
  accent?: string
  className?: string
  style?: CSSProperties
}

// Идея компонента: каскад, который переживёт выключенный JS. Ветки — нативные
// <details>, лист — radio с общим именем, поэтому дерево можно положить в
// обычную форму и отправить POST'ом. Выбранная ветка подсвечивается по всей
// глубине через :has(input:checked): без этого при свёрнутых уровнях
// непонятно, где именно стоит отметка.
