# Expanded Search (Notchset): prompt.md (v1.0.0)

- id: `search-expand` · version 1.0.0 · component · pro (Pro)
- category: Navigation
- build: Base UI (one set of files; its dependencies follow the build)
- install (this build): `npx shadcn@latest add @beautiful-ui-pro/search-expand`
- npm dependencies: none
- registry dependencies: utils, https://beautiful-ui.dev/r/notchset-foundation.json
- docs: https://beautiful-ui.dev/components/search-expand
- The install command carries everything this item needs (files, CSS, tokens, npm and registry dependencies). Prefer it to copying source by hand.

An app bar whose search key widens across the whole bar as the nav slides away, with a results sheet that unrolls below in scopes with live counts, grouped results and underlined matches.

## Build it
- Stack: React 19 (`ref` is a plain prop), TypeScript, Tailwind CSS v4 utilities, a shadcn-initialised project with the `@/*` alias.
- Packages: none beyond React.
- Files: `components/ui/notchset/search-expand.tsx`; shared code: `lib/beautiful-ui/notchset/instrument.tsx`, `lib/beautiful-ui/notchset/root.ts`.
- Registry dependencies, installed with it automatically: shadcn `utils` (cn), `notchset-foundation`.
- Builds: one set of files for both, but its dependencies come in Base UI and Radix builds. Install the one that matches the project (see Install): a free item's bare URL installs the Base UI build of it and its dependencies.
- Exports to keep: `SearchExpand`, and every exported type.
- CSS: the install adds the notchset foundation (tokens, keyframes, motion levels) to your global stylesheet once. Nothing to import by hand.
- Re-running `add` (or `--overwrite`) re-applies those rules: put overrides in your own CSS, never in the installed rules.
- Tokens: retheme with the `--notchset-*` custom properties (`--notchset-check`, `--notchset-control-edge`, `--notchset-draw-from`, `--notchset-ease-bloom`, `--notchset-ease-travel`, `--notchset-fade`, `--notchset-focus-color`, `--notchset-focus-inset`, `--notchset-life-from`, `--notchset-life-ms`, `--notchset-node-blink`, `--notchset-node-bloom`, `--notchset-node-delay`, `--notchset-plate-color`, `--notchset-rise-from`, `--notchset-rule`, `--notchset-scroll`, `--notchset-signal`, `--notchset-sweep-to`). Never add Tailwind colour classes inside the component.

```tsx
import { SearchExpand, type SearchExpandGroup } from "@/components/ui/notchset/search-expand";
```

## Parts

| Part | data-slot | What it is for |
|---|---|---|
| `SearchExpand` | `search-expand-frame` | The frame. |
| `key` | `search-expand` | The widening key. |

Style a part with `[data-slot="<slot>"]` selectors or its `className`; keep the attributes when editing.

## Sound
- Keep every `data-slot` and `data-sound` attribute: the sound layer reads them.
- Installing this item adds no audio. Nothing plays until the app mounts `SoundProvider` once (install: `npx shadcn@latest add https://beautiful-ui.dev/r/notchset-sound.json`, import from `@/components/ui/notchset/sound-provider`); `useSound()` gives `muted` and `setMuted` for a mute control. Without a provider the audio engine never loads.

## Match the original
- Read `components/ui/notchset/search-expand.tsx` as the reference implementation before changing or recreating anything, and match it: sizes, colours per theme, motion timings, copy and behaviour.
- If you deviate (a prop you can't honour, a style you changed, a dependency you swapped), say so in your reply, part by part.
- Keep the accessibility contract, the keyboard map and the motion levels listed below.

## Use it when
- expanded search, global search, command search, app bar search, search everything, Notchset
- Product-wide search from an app bar: agents, runs, traces, docs

### Not when
- Picking one item from a known list: use Search Projects or Combobox

## Mistakes
- Keep result labels short: rows are one line

## Usage

```tsx
"use client";

import * as React from "react";
import { SearchExpand, type SearchExpandGroup } from "@/components/ui/notchset/search-expand";

const results: SearchExpandGroup[] = [
  { id: "agents", label: "AGENTS", items: [{ label: "Planner", meta: "PROD" }, { label: "Triage", meta: "STAGING" }] },
  { id: "runs", label: "RUNS", items: [{ label: "run_8f3a1", meta: "OK · 2.1S" }, { label: "run_8f3a2", meta: "FAILED", tone: "signal" }] },
];

export function AppBar({ children }: { children: React.ReactNode }) {
  return (
    <SearchExpand
      nav={
        <nav className="flex gap-4 font-mono text-xs">
          <a href="/agents">AGENTS</a>
          <a href="/runs">RUNS</a>
        </nav>
      }
      groups={results}
    >
      {children}
    </SearchExpand>
  );
}
```

## Props

| Prop | Type | Default | What it does |
|---|---|---|---|
| `nav` | `ReactNode` |  | The bar's left side; it fades away while searching. |
| `groups` | `{ id, label, items: { label, meta?, tone?, hollow?, onSelect? }[] }[]` |  | Results by scope. |
| `children` | `ReactNode` |  | The page; it dims while searching. |
| `hotkey` | `string` |  | Opens search from anywhere (/). |

## Customising
- Colours: the component reads your shadcn tokens (`--background`, `--foreground`, `--border` …), refined by the `--notchset-*` tokens. The signal colour is `--notchset-signal` (it falls back to `--destructive`). Set tokens on `:root`, or on any container to retheme one area.
- Dark mode follows the `.dark` class on an ancestor (the shadcn and next-themes convention).
- Update later by re-running the install with `--overwrite` (review the diff if you edited it). Changelog: https://beautiful-ui.dev/r/changelog.json

## Keyboard

| Keys | Action |
|---|---|
| / | Open |
| Esc | Close |
| Tab | Move through scopes and results |

## Performance

- The key widens and the sheet unrolls with CSS; results filter synchronously as you type.

## Responsive

- Fills the frame you give it; scopes scroll sideways if they run out of room, results scroll within the sheet.

## Motion inventory

| Interaction | What moves |
|---|---|
| Open | The key widens (420ms) as the nav slides away; the input fades in after 220ms; the sheet unrolls (400ms after 160ms); the page dims to 25% |
| Scope | The 2px underline scales in (300ms); groups settle in 60ms apart |
| Close | Everything reverses in 160–300ms |

## Accessibility contract (preserve when editing)
- The key is aria-expanded and controls the sheet; scopes are a tablist
- Esc, the ESC chip or a click outside closes it
- Results are buttons, reachable with Tab

## Install

```bash
npx shadcn@latest add @beautiful-ui-pro/search-expand
```

Pro item: needs the `@beautiful-ui-pro` registry in `components.json` and `BEAUTIFUL_UI_TOKEN` in `.env.local` (https://beautiful-ui.dev/account). Setup: https://beautiful-ui.dev/docs/pro. Your components.json `style` picks the build: radix-*, new-york and default get Radix, base-* gets Base UI.

- Built on shadcn/ui (https://ui.shadcn.com)

The notchset foundation (the tokens listed above, keyframes and motion levels) installs once with the first component; its CSS is public at https://beautiful-ui.dev/r/notchset-foundation.json.
