# Install and place "kanban-004" (Collapsible 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/kanban-004.json

Registry item: https://vibeui.ru/r/kanban-004.json
Installs to: components/vibeui/kanban-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
A board where a column collapses into a narrow strip with a vertical name and a counter, and a move into a collapsed column expands it instead of failing.

A board with collapsible columns: a collapsed one turns into a strip with its name and counter yet stays a drop target. Zero dependencies, one file.

## 3. How to use it
import { Kanban004 } from "@/components/vibeui/kanban-004"

<Kanban004 collapsed={["Done"]} columns={["Queue", "Done"]} />

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-kanban-004-* palette — do not swap it for your theme tokens
- the hidden attribute on a collapsed column's list: invisible cards must not catch focus
- aria-expanded on the header button — otherwise the collapsed state is inaudible
- expanding a column when a card is moved into it: a hidden target you cannot reach is a trap
- the counter on the collapsed strip: without it the column looks empty
- the arrow buttons on the card — dragging is unavailable from a keyboard

## 6. You may change
- the columns and cards arrays
- collapsed — which columns start collapsed
- the onChange handler and the accent through the accent prop
- the width of an expanded and of a collapsed column

## 7. Rules
- The collapsed set lives inside the component: the collapsed prop only seeds it.
- The vertical name relies on writing-mode — check long column titles.
- Order inside a column does not change: the move only sets membership.
- 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/kanban-004.json
https://vibeui.ru/r/kanban-004.json

Компонент самодостаточен: один файл, без зависимостей, собственная палитра в локальных переменных --vibeui-kanban-004-*. Клиентский: "use client" ради состояния доски и набора свёрнутых колонок. Колонки лежат во флексе, свёрнутая получает фиксированную узкую основу, а её заголовок переворачивается через writing-mode. Список карточек свёрнутой колонки помечен hidden, поэтому выпадает и из отрисовки, и из последовательности фокуса. Кнопка заголовка несёт aria-expanded, все изменения объявляются в живой области role=status.

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, DragEvent } from "react"

export type Kanban004Card = {
  id: string
  title: string
  column: string
}

export type Kanban004Props = Omit<
  ComponentPropsWithoutRef<"div">,
  "children" | "onChange"
> & {
  columns?: string[]
  cards?: Kanban004Card[]
  collapsed?: string[]
  onChange?: (cards: Kanban004Card[]) => void
  accent?: string
}

// Идея компонента: доска, где ненужную сейчас колонку сворачивают в узкую
// полосу. Свёрнутая колонка не исчезает: её имя стоит вертикально, счётчик
// остаётся на виду, а карточки внутри скрыты hidden — так они выпадают и из
// последовательности фокуса, иначе табом можно уехать в невидимое. Перенос в
// свёрнутую колонку не отклоняется, а разворачивает её: спрятанная цель, куда
// нельзя попасть, — это не свёртка, а ловушка. Стрелочные кнопки на карточке
// дают тот же перенос с клавиатуры, результат объявляется вслух.
