    `Optional arrow to point to content.`,
    `Keeps within bounds of page.`,
    `Can be placed into 12 anchor positions.`,

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

<Notice>
  Note: Popovers are not a recommended pattern for mobile apps, and so aren't supported on
  native. Instead you can use Adapt and render them as a Sheet, or just conditionally
  render them. We landed support for them at one point, but we need the community to
  contribute tests in order to support them for mobile again.
</Notice>

## 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 />

    {/* Optional: Control focus behavior */}
    <Popover.FocusScope loop trapped focusOnIdle={true}>
      <Popover.Content>
        <Popover.Arrow />
        <Popover.Close />
        {/* ScrollView is optional, can just put any contents inside if not scrollable */}
        <Popover.ScrollView>{/* ... */}</Popover.ScrollView>
        {/* ... */}
      </Popover.Content>
    </Popover.FocusScope>

    {/* 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>
)
```

For most of these properties, you'll want to reference the
[floating-ui docs](https://floating-ui.com/docs/getting-started).

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

### 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

Extends PopperContent which extends SizableStack which extends a YStack (see
[Stacks](/docs/components/stacks)).

Also extends

Used to display the content of the popover.

    {
      name: 'enableAnimationForPositionChange',
      type: 'boolean',
      description:
        'Disabled animate presence animations in favor of regular animation, useful for doing sliding popovers.',

      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.FocusScope

Provides access to the underlying FocusScope component used by Popover for focus
management. Can be used to control focus behavior from a parent component.

<PropsTable
  data={[
    {
      name: 'enabled',
      type: 'boolean',
      default: 'true',
      description: `Whether focus management is enabled`,
    },
    {
      name: 'loop',
      type: 'boolean',
      default: 'false',
      description: `When true, tabbing from last item will focus first tabbable and shift+tab from first item will focus last tabbable`,
    },
    {
      name: 'trapped',
      type: 'boolean',
      default: 'false',
      description: `When true, focus cannot escape the focus scope via keyboard, pointer, or programmatic focus`,
    },
    {
      name: 'focusOnIdle',
      type: 'boolean | number',
      default: 'false',
      description: `When true, waits for idle before focusing. When a number, waits that many ms. This prevents reflows during animations`,
    },
    {
      name: 'onMountAutoFocus',
      type: '(event: Event) => void',
      description: `Event handler called when auto-focusing on mount. Can be prevented`,
    },
    {
      name: 'onUnmountAutoFocus',
      type: '(event: Event) => void',
      description: `Event handler called when auto-focusing on unmount. Can be prevented`,
    },
  ]}
/>

### 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.
