Popovers are a great way to show content that's only visible when trigger is pressed, floating above the current content.

## Installation

Popover is already installed in `hanzogui`, or you can install it independently:

```bash
npm install @hanzogui/popover
```

### PortalProvider

When rendering into root of app instead of inline, you'll first need to install the `@hanzogui/portal` package:

```bash
npm install @hanzogui/portal
```

Then add `PortalProvider` to the root of your app:

```tsx fileName="App.tsx"
import { PortalProvider } from '@hanzogui/portal'
import YourApp from './components/YourApp'

function App() {
  return (
    <PortalProvider shouldAddRootHost>
      <YourApp />
    </PortalProvider>
  )
}

export default App
```

<PropsTable
  data={[
    {
      name: 'shouldAddRootHost',
      type: 'boolean',
      required: false,
      description: `Defines whether to add a default root host or not.`,
    },
  ]}
/>

## Anatomy

```tsx
import { Popover, Adapt } from '@hanzo/gui' // or '@hanzogui/popover'

export default () => (
  <Popover>
    <Popover.Trigger />

    <Popover.Content>
      <Popover.Arrow />
      <Popover.Close />
      {/* ScrollView is optional, can just put any contents inside if not scrollable */}
      <Popover.ScrollView>{/* ... */}</Popover.ScrollView>
      {/* ... */}
    </Popover.Content>

    {/* optionally change to sheet when small screen */}
    {/* you can also use <Popover.Adapt /> */}
    <Adapt when="maxMd">
      <Popover.Sheet>
        <Popover.Sheet.Overlay />
        <Popover.Sheet.Frame>
          <Popover.Sheet.ScrollView>
            <Adapt.Contents />
          </Popover.Sheet.ScrollView>
        </Popover.Sheet.Frame>
      </Popover.Sheet>
    </Adapt>
  </Popover>
)
```

<Notice>
  If using `modal={true}` (which is `true` by default), refer to the [PortalProvider
  installation](/ui/popover/1.83.0#portalprovider) for more information.

### Popover.Arrow

Popover.Arrow can be used to show an arrow that points at the Trigger element. In order for the Arrow to show you must have a Trigger element within your Popover. Arrows extend YStack, see [Stacks](/docs/components/stacks).

### Popover.Trigger

Used to trigger opening of the popover when uncontrolled, just renders a YStack, see [Stacks](/docs/components/stacks).

### Popover.Content

Renders as SizableStack which is just a YStack (see [Stacks](/docs/components/stacks)) with an extra `size` prop that accepts any `SizeTokens`.

Used to display the content of the popover.

<PropsTable
  data={[
    {
      name: 'size',
      type: 'SizeTokens',
      required: false,
    },
    {
      name: 'unstyled',
      required: false,
      type: `boolean`,
      description: `Removes all default Gui styles.`,
    },
  ]}
/>

### Popover.Anchor

Renders as YStack, see [Stacks](/docs/components/stacks).

When you want the Trigger to be in another location from where the Popover attaches, use Anchor. When used, Anchor is where the Popover will attach, while Trigger will open it.

### Popover.Sheet

When used with `Adapt`, Popover will render as a sheet when that breakpoint is active.

See [Sheet](/docs/components/sheet) for more props.

Must use `Adapt.Contents` inside the `Popover.Sheet.Frame` to insert the contents given to `Popover.Content`

### Popover.ScrollView

Must be nested inside Content. Renders as a plain React Native ScrollView. If used alongside `<Adapt />` and Sheet, Gui will automatically know to remove this ScrollView when swapping into the Sheet, as the Sheet must use it's own ScrollView that handles special logic for interactions with dragging.
