# Install and place "cascader-018" (Snap Columns) 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-018.json

Registry item: https://vibeui.ru/r/cascader-018.json
Installs to: components/vibeui/cascader-018.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
An equipment-node cascader whose level columns live in a scroll-snap strip: on a narrow width they scroll instead of collapsing into a stack.

A column cascader for tight places: the columns sit in a horizontal strip with scroll-snap and page through like slides. The equipment tree shows each node's status as a dot — running, under repair, stopped — so a work order lands on the right node straight away. Zero dependencies, one file, its own palette.

## 3. How to use it
import { Cascader018 } from "@/components/vibeui/cascader-018"

<Cascader018 label="Equipment node" />

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-018-* palette — do not swap it for your theme tokens (bg-muted, border-border and the like)
- scroll-snap-type together with the fixed column width: without snapping a column stops mid-way and reads half-cut
- rebuilding the columns from path on every render instead of storing them in state — otherwise an upper-level choice leaves ghost columns
- the sticky level heading: while scrolling a long list it stops being obvious which level you are in
- the status spelled out in the aria-label next to the coloured dot — colour is neither read aloud nor safe for colour blindness
- three status hues that differ in lightness, not only in tone
- the summary with aria-live="polite" showing the whole path and the leaf status

## 6. You may change
- label — the heading above the column strip
- tree — the equipment tree, of any depth
- defaultPath — the path expanded at first render
- levelLabels — the level captions in the column headers
- onSelect — the handler for the path as an array of strings
- accent — the highlight colour of the current node

## 7. Rules
- The column width is in rem: on very narrow screens shrink it along with the font, or less than half a row shows.
- Horizontal scrolling with a mouse is not obvious: on desktop consider adding paging buttons.
- Status arrives as a prop and does not refresh itself — live data needs a subscription.
- Beyond four levels the strip gets lost: a searchable tree suits that better.

## 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-018.json
https://vibeui.ru/r/cascader-018.json

Компонент самодостаточен: один файл, ноль зависимостей, собственная палитра в локальных переменных --vibeui-cascader-018-*. Клиентский: путь по дереву живёт одним массивом в useState. Колонки не хранятся в состоянии, а собираются проходом по path на каждом рендере, поэтому выбор на верхнем уровне автоматически отсекает лишние колонки. Полоса колонок — flex с overflow-x и scroll-snap-type: x mandatory, каждая колонка фиксированной ширины 9.5rem со scroll-snap-align: start, поэтому на телефоне колонки листаются как страницы, а не сжимаются в нечитаемые полоски. Заголовок уровня прилипает через position: sticky. Статус узла показан точкой и продублирован словами в aria-label.

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 { ComponentPropsWithoutRef, CSSProperties } from "react"

export type Cascader018Status = "ok" | "repair" | "off"

export type Cascader018Node = {
  name: string
  status?: Cascader018Status
  children?: Cascader018Node[]
}

export type Cascader018Props = Omit<
  ComponentPropsWithoutRef<"section">,
  "children" | "onSelect"
> & {
  label?: string
  tree?: Cascader018Node[]
  defaultPath?: string[]
  levelLabels?: string[]
  onSelect?: (path: string[]) => void
  accent?: string
}

// Идея компонента: у каскадера с тремя колонками на узкой ширине выбор
// один — либо ломать колонки в столбик, либо прокручивать их горизонтально.
// Здесь колонки живут в полосе со scroll-snap: после выбора уровня следующая
// колонка встаёт по краю сама, как в файловом менеджере. У каждого узла
// оборудования есть статус точкой — по нему видно, куда вообще нельзя вешать
// заявку.
