# Item (Lumen Halo): prompt.md (v1.0.0)

- id: `lumen-item` · version 1.0.0 · component · pro (All-Access)
- category: Data
- build: Base UI (this item also ships a Radix build)
- install (this build): `npx shadcn@latest add @beautiful-ui-pro/lumen-item`
- npm dependencies: @base-ui/react@^1, class-variance-authority@^0.7
- registry dependencies: utils, @beautiful-ui/lumen-separator, https://beautiful-ui.dev/r/lumen-foundation.json
- docs: https://beautiful-ui.dev/components/lumen-item
- The install command carries everything this item needs (files, CSS, tokens, npm and registry dependencies). Prefer it to copying source by hand.

A row for a list of things (a source, a member, a file): bare, outlined or on glass, with a media tile, a title and actions, lifting slightly as a link. shadcn's Item, cut from Lumen glass.

## Build it
- Stack: React 19 (`ref` is a plain prop), TypeScript, Tailwind CSS v4 utilities, a shadcn-initialised project with the `@/*` alias.
- Packages: `@base-ui/react@^1`, `class-variance-authority@^0.7` (Base UI build); `class-variance-authority@^0.7`, `radix-ui@^1` (Radix build).
- Files: `components/ui/lumen/item.tsx`.
- Registry dependencies, installed with it automatically: shadcn `utils` (cn), `lumen-separator`, `lumen-foundation`.
- Builds: separate Base UI and Radix files. 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: `Item`, `ItemMedia / ItemContent / ItemTitle / ItemDescription`, `ItemActions / ItemHeader / ItemFooter`, `ItemGroup / ItemSeparator`, and every exported type.
- CSS: the install merges this item's rules (the registry `css` field) into your global stylesheet, in `@layer components`, and adds the lumen foundation (tokens, keyframes, motion levels) 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 `--lumen-*` custom properties (`--lumen-accent`, `--lumen-accent-text`, `--lumen-bad`, `--lumen-bad-text`, `--lumen-focus`, `--lumen-good`, `--lumen-good-text`, `--lumen-hairline`, `--lumen-ink`, `--lumen-muted-ink`, `--lumen-series-1`, `--lumen-series-2`, `--lumen-series-3`, `--lumen-series-4`, `--lumen-series-5`, `--lumen-series-6`, `--lumen-warn`, `--lumen-warn-text`); this item's CSS also reads `--lumen-font-sans`, `--lumen-radius-k`. Never add Tailwind colour classes inside the component.

```tsx
import { Item, ItemActions, ItemContent, ItemDescription, ItemMedia, ItemTitle } from "@/components/ui/lumen/item";
```

## Parts

| Part | data-slot | What it is for |
|---|---|---|
| `Item` | `item` | The row. |
| `ItemMedia / ItemContent / ItemTitle / ItemDescription` | `item-media` | Its parts. |
| `ItemActions / ItemHeader / ItemFooter` | `item-actions` | More. |
| `ItemGroup / ItemSeparator` | `item-group` | Lists. |

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 `GlassSoundProvider` once (install: `npx shadcn@latest add https://beautiful-ui.dev/r/glass-sound.json`, import from `@/components/beautiful-ui/glass-sound`); `GlassSoundToggle` is its mute control. Without a provider the audio engine never loads.

## Match the original
- Read `components/ui/lumen/item.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
- item, list item, row, list row, settings row, shadcn item, Lumen
- Lists of things with an icon, a title, a line and actions

### Not when
- Tabular data: use Table

## Mistakes
- One primary action per row

## Usage

```tsx
import { Item, ItemActions, ItemContent, ItemDescription, ItemMedia, ItemTitle } from "@/components/ui/lumen/item";

<Item variant="outline">
  <ItemMedia variant="icon">…</ItemMedia>
  <ItemContent>
    <ItemTitle>Postgres</ItemTitle>
    <ItemDescription>Synced 2 min ago</ItemDescription>
  </ItemContent>
  <ItemActions>…</ItemActions>
</Item>
```

## Props

| Prop | Type | Default | What it does |
|---|---|---|---|
| `variant / size` | `"default" \| "outline" \| "muted" / "default" \| "sm" \| "xs"` |  | As shadcn. |
| `render / asChild` | `per base` |  | Make the row a link. |

## Customising
- Colours: set the `--lumen-*` tokens on `:root`, or on a container with the `lumen-scope` class to retheme one area. Add the `lumen-inherit` class to follow your shadcn palette instead (`--chart-N`, `--destructive`).
- 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 |
|---|---|
| Tab | To the row (as a link) or its actions |

## Motion inventory

| Interaction | What moves |
|---|---|
| Hover (link) | Lifts 1px with a soft glow |

## Accessibility contract (preserve when editing)
- ItemGroup is a list; make actionable rows links or buttons

## Install

```bash
npx shadcn@latest add @beautiful-ui-pro/lumen-item
```

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.

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

The lumen 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/lumen-foundation.json.
