I have a DataGrid with a PopUpMenuButton itemEditor. When the DataGrid is full,
and I click one of the bottom row items, the Menu is properly displayed -
popping above the Button, so that all items are displayed. However, when I
click an item in the middle of the DataGrid, the Menu is popped below the
Button, and the last few items are hidden. I was wondering if anyone had any
suggestions on how to fix this. Is there someway to make the menu scroll when
it is going be longer than the component allows?

Thanks.
