# Popover

Open arbitrary content in a panel anchored to a trigger button.

## Install

```sh
npx shadcn@4.21.0 add lr-run/dir-ui/popover#v0.1.3
```

[Registry item with source and dependencies](https://github.com/lr-run/dir-ui/blob/v0.1.3/registry.json)

Requires React 19, Tailwind CSS 4 and shadcn initialized with Base UI. Registry target placeholders resolve through components.json: @ui, @components, @hooks and @lib. Imports below use the conventional @/ prefix for illustration; the CLI rewrites them to your configured aliases. Shared components are installed once through registryDependencies. The installer merges shared theme rules into the stylesheet configured in components.json. Existing files are never forcibly overwritten; review CLI conflicts before accepting changes. No Dir runtime is required.

## PopoverPanel

```tsx
import { PopoverPanel } from '@/components/ui/popover-panel.tsx'
```

| Prop | Type | Default / required | Notes |
| --- | --- | --- | --- |
| trigger | ReactElement | Required | A button or other element; render merges its events and ref. |
| title / children | ReactNode | Required |  |
| description | ReactNode | — |  |
| open / onOpenChange | boolean / (open: boolean) => void | Uncontrolled |  |
| align | 'start' \| 'center' \| 'end' | 'start' |  |
| side | 'top' \| 'bottom' \| 'left' \| 'right' | 'bottom' |  |
| width | number \| string | 320 |  |

Escape or an outside click closes the panel and restores trigger focus. Lower-level Popover, Trigger, and Content exports are available from components/ui/popover.tsx.
