North pane
West pane
South pane
East pane

This pane has a scrollbar. Note how the scrollbar disappears and content 'overflows' into the South pane when you you mouse-over the Pop-Up.

So the allowOverflow method is best used only for panes that do not scroll, like a toolbar or menubar.

Center pane

The Pop-Up and Drop-Down lists demonstrate the allowOverflow() utility

The allowOverflow() method is attached differently in each pane: North, West & East

NOTE: The allowOverflow method is intended as a last resort - used only when there is no other way to make a popup work.
