# Install and place "cascader-016" (Place Picker) 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-016.json

Registry item: https://vibeui.ru/r/cascader-016.json
Installs to: components/vibeui/cascader-016.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 “building → floor → room” picker where each level is shaped by its nature: tabs, chips and a tile grid with capacity.

A cascader for spaces: buildings as tabs, floors as chips, rooms as tiles in a grid. The last level is spatial, and a tile grid reads closer to a floor plan than a list row: capacity is visible, so is what is taken. Zero dependencies, one file, its own palette.

## 3. How to use it
import { Cascader016 } from "@/components/vibeui/cascader-016"

<Cascader016 label="Meeting place" defaultRoom="A-201" />

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-016-* palette — do not swap it for your theme tokens (bg-card, bg-muted and the like)
- different elements for different levels: tabs, chips and tiles read as three different questions, not three identical lists
- the auto-fill minmax grid: the column count follows the component width, not the window width
- native disabled on busy rooms together with the “taken” caption — colour alone does not explain the block
- capacity in the caption and in the aria-label: a meeting room is picked by the number of seats
- clearing floor and room when the building changes: otherwise a room from another block survives
- the summary with aria-live="polite" assembling the full path: “A-201” on its own means nothing

## 6. You may change
- label — the heading above the levels
- buildings — the tree of buildings, floors and rooms with capacity and a busy flag
- defaultRoom — the room selected at first render
- onSelect — the handler; it receives building, floor and room
- accent — the colour of the active chip and the selected tile
- the minimum tile width in the grid when room names run longer

## 7. Rules
- The tabs here have no WAI-ARIA arrow-key navigation: with more than five buildings add it deliberately.
- Occupancy arrives as a prop and does not refresh itself: live data needs your own polling or subscription.
- Do not sort rooms by capacity: people search by number, and the number maps to location.
- For a campus of a dozen blocks tabs do not scale — that case needs building search.

## 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-016.json
https://vibeui.ru/r/cascader-016.json

Компонент самодостаточен: один файл, ноль зависимостей, собственная палитра в локальных переменных --vibeui-cascader-016-*. Клиентский: здание, этаж и комната живут в трёх useState, смена верхнего уровня обнуляет нижние. Уровни намеренно оформлены разными элементами: здания — role="tablist" с aria-selected, этажи — кнопки-фишки с aria-pressed, комнаты — grid с auto-fill minmax(6.5rem, 1fr), который сам решает число колонок по ширине карточки, а не по ширине окна. Занятая комната получает нативный disabled и собственную подложку, вместимость подписана и продублирована в aria-label вместе со статусом. Итог внизу собирает полный путь и вместимость и объявляется через aria-live.

Component source

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

// Идея компонента: «здание → этаж → комната» — это не список списков,
// а три разных по природе выбора. Здания сделаны вкладками, этажи —
// фишками, а комнаты сеткой плиток с вместимостью: последний уровень
// пространственный, и плитка ближе к плану этажа, чем строка списка.
