# Install and place "cascader-001" (Cascader Select) 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-001.json

Registry item: https://vibeui.ru/r/cascader-001.json
Installs to: components/vibeui/cascader-001.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 cascading select: level by level on native selects, with the next level appearing only after a choice on the current one.

A cascading select: native lists per level, the chosen path spelled out below and lower levels reset when an upper one changes. Zero dependencies, one file.

## 3. How to use it
import { Cascader001 } from "@/components/vibeui/cascader-001"

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-001-* palette — do not swap it for your theme tokens
- native selects: the phone's system picker and keyboard support come free
- revealing the next level only after a choice: an empty list looks broken
- resetting lower levels when an upper one changes — otherwise the path becomes impossible
- the path spelled out below: once the lists close nothing else shows the result
- aria-live on the path line

## 6. You may change
- the tree and the label
- the onChange handler
- the accent through the accent prop
- the block width

## 7. Rules
- There is no search across levels: for long lists use autocomplete-001.
- Depth is unlimited, but past the fourth level the choice stops reading.
- An intermediate level cannot be the final answer: add an "entire section" option if you need it.
- 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-001.json

Компонент самодостаточен: один файл, без зависимостей, собственная палитра в локальных переменных --vibeui-cascader-001-*. Клиентский: "use client" ради пути выбора. Каждый уровень — нативный select, поэтому на телефоне открывается системный выбор, а клавиатура работает без своего кода. Уровни считаются из дерева по текущему пути, лишние отбрасываются при смене верхнего уровня.

Component source

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

"use client"

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

export type Cascader001Node = {
  label: string
  children?: Cascader001Node[]
}

export type Cascader001Props = Omit<
  ComponentPropsWithoutRef<"div">,
  "children" | "onChange"
> & {
  label?: string
  tree?: Cascader001Node[]
  onChange?: (path: string[]) => void
  accent?: string
}

// Идея компонента: выбор по уровням вместо длинного списка. Каждый уровень —
// нативный select, поэтому на телефоне открывается системный выбор, а с
// клавиатуры всё работает без единой строки своего кода. Следующий уровень
// появляется только после выбора на текущем, а не стоит пустым: пустой список
// выглядит сломанным. Выбранный путь показан строкой — иначе после закрытия
// списков непонятно, что именно выбрано.
