# Install and place "cascader-007" (Checked Branches) 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-007.json

Registry item: https://vibeui.ru/r/cascader-007.json
Installs to: components/vibeui/cascader-007.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 multi-select cascader: ticking a parent switches on the whole branch, a partial selection shows as the third checkbox state, and the result is echoed as chips below.

A cascader with checkboxes and inheritance: a parent toggles its whole branch, a partial selection reads as the third state, and picks are echoed as chips. One file, zero dependencies.

## 3. How to use it
import { Cascader007 } from "@/components/vibeui/cascader-007"

<Cascader007 heading="Newsletter topics" accent="#4338ca" />

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-007-* palette — do not swap it for your theme tokens
- deriving the parent state from its children: a parent with its own state eventually drifts from the branch
- the third state through a ref: indeterminate has no HTML attribute and cannot be set from markup
- the "picked of total" counter on the parent — a collapsed branch otherwise hides how much is ticked
- the chips below: in a scrolling list the selection cannot be taken in at a glance otherwise
- the panel's own light surface: dark text disappears on the dark catalogue card

## 6. You may change
- the panel heading through heading
- the accent colour through accent
- the set of branches through groups
- the height of the scrolling tree in CSS

## 7. Rules
- The tree here is exactly two levels: a third one needs recursion and indeterminate recomputed over the subtree.
- A pick is keyed by the "parent → child" string, so identically named leaves from different branches never collide.
- Clicking a partially ticked parent completes the branch instead of clearing it: familiar, but verify it on your data.
- 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-007.json
https://vibeui.ru/r/cascader-007.json

Компонент самодостаточен: один файл, без зависимостей, собственная палитра в локальных переменных --vibeui-cascader-007-*. Клиентский: список выбранных ключей «родитель → ребёнок» живёт в useState. Родительская галочка не хранит своего состояния — checked и indeterminate вычисляются из детей, поэтому рассинхронизация невозможна. Третье состояние ставится ref-колбэком: у input.indeterminate нет HTML-атрибута. Строки подсвечиваются через :has(input:focus-visible), поэтому фокус виден на всей строке, а не на самом чекбоксе.

Component source

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

"use client"

import { useState } from "react"
import type { CSSProperties } from "react"

export type Cascader007Group = {
  label: string
  children: string[]
}

export type Cascader007Props = {
  heading?: string
  groups?: Cascader007Group[]
  accent?: string
  className?: string
  style?: CSSProperties
}

// Идея компонента: каскад с множественным выбором. Галочка на родителе
// включает всю ветку, снятие — выключает; частичный выбор показан третьим
// состоянием (indeterminate), иначе половинчатая ветка выглядит как
// невыбранная и её отмечают повторно. Итог собран чипами внизу: по дереву
// с прокруткой нельзя понять, сколько всего набрано.
