Nested Commands

A two-level palette: Enter on a command that takes a parameter drills into its subcommands, and Backspace on an empty query steps back out.

  1. 1. Copy the link.
  2. 2. Write to your agent in your own words and drop the link into the sentence.
  3. 3. The agent opens the link and installs the component from the registry.

# Install and place "command-004" (Nested Commands) 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/command-004.json

Registry item: https://vibeui.ru/r/command-004.json
Installs to: components/vibeui/command-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 two-level palette: Enter on a command that takes a parameter drills into its subcommands, and Backspace on an empty query steps back out.

A palette with nested subcommands: Enter drills in, a breadcrumb chip sits next to the field, and Backspace on an empty query steps back. Zero dependencies, one file.

## 3. How to use it
import { Command004 } from "@/components/vibeui/command-004"

<Command004 commands={[{ label: "Change theme", children: ["Light", "Dark"] }]} />

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-command-004-* palette — do not swap it for your theme tokens
- the level chip beside the field rather than breadcrumbs above the panel: context belongs where the caret is
- stepping back with Backspace on an empty query — the familiar gesture that saves aiming at a close button
- clearing the query when drilling in: the old filter does not apply to subcommands
- the chevron marking rows that nest: without it Enter behaves unpredictably
- the role=combobox plus aria-activedescendant pairing: focus stays in the field

## 6. You may change
- the commands array and its nested children
- the field hint through the placeholder prop
- the footer text with the key hints
- the accent through the accent prop

## 7. Rules
- There are exactly two levels: for a deeper tree keep the path as an array instead of one parent.
- Escape clears the query first and only then steps back — those are two distinct undo steps.
- Running a command only prints into the footer here: hook your own handler into choose.
- 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/command-004.json
https://vibeui.ru/r/command-004.json

Компонент самодостаточен: один файл, без зависимостей, собственная палитра в локальных переменных --vibeui-command-004-*. Клиентский: "use client" ради состояния уровня и запроса. Команда с массивом children не выполняется, а открывает второй уровень: запрос сбрасывается, слева от поля появляется чип-крошка с именем родителя, список сменяется подкомандами. Возврат назад повешен на Backspace при пустом запросе и на Escape, а также на крестик в чипе. Роли combobox, listbox и option объявлены явно.

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,
  KeyboardEvent,
} from "react"

export type Command004Command = {
  label: string
  children?: string[]
}

export type Command004Props = Omit<
  ComponentPropsWithoutRef<"div">,
  "children"
> & {
  commands?: Command004Command[]
  placeholder?: string
  accent?: string
}

// Идея компонента: двухуровневая палитра. Команда с параметром («Сменить
// тему» → какую именно) не помещается в одну строку списка, поэтому Enter по
// такой строке не запускает её, а входит на второй уровень: слева от поля
// появляется чип-хлебная крошка, запрос сбрасывается, список сменяется
// подкомандами. Backspace на пустом запросе выходит обратно — это привычный
// жест, и он снимает необходимость целиться в крестик.
