# overflowPresentationSource

The item you can use as an anchor to present a custom UI from the overflow menu button.

## Declaration

```swift
var overflowPresentationSource: (any UIPopoverPresentationControllerSourceItem)? { get }
```

## Discussion

Discussion If the overflow menu button for the navigation item is visible, this property returns a non-nil item that you can use as a presentation source — for example, to present a custom popover that anchors to the overflow menu button. Otherwise, this property returns nil.
