title: "Popover"
description: "A non-modal panel anchored to a trigger."

Interactive preview: https://ui.coderocket.app/docs/components/popover

## Usage

Get this component from a [saved library export](/docs/export) or the [connected CLI](/docs/agents). The imports below refer to local files installed in your app.

Import `styles/components.css`, then `styles/theme.css` once. Wrap your app in `ThemeScope` from `components/ui/utils` so typography, focus and overlays share the theme. The [installation guide](/docs/export) covers runtime dependencies and React/Next.js setup.

```tsx
import { Popover } from './components/ui/popover';

<Popover trigger="Set dimensions" title="Dimensions"><Input aria-label="Width" placeholder="Width"/></Popover>
```

## Design system

This component consumes your semantic colors, spacing, typography and shape tokens. Import the compiled styles and your theme once as described in [Export](/docs/export).

Dependencies: [Input](/docs/components/input).

## Behavior and accessibility

- Provide meaningful labels for interactive controls.
- Connect action callbacks to your application logic.
- Verify keyboard navigation and contrast in your application.

Status: **experimental** during early access. Sample previews do not send emails, process payments or upload files to a service.
