# show(relativeTo:)

```

## Parameters

## Discussion

Discussion Use this method to display a popover relative to a toolbar item. When the item is in the overflow menu, the popover presents itself from another appropriate affordance in the window. See show(relativeTo:of:preferredEdge:) for popover behavior. This method raises an invalidArgumentException if it can’t locate the toolbar item. This could occur if the item isn’t in a toolbar, or because the toolbar isn’t in the window.
