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?
