I have a Canvas with one Combobox and one Button within. I'm trying to visually append the button below the dropdown so the button looks like it's part of the dropdown. On the DropdownEvent.OPEN event, the button is moved to be below that dropdown. On the DropdownEvent.CLOSE event, the button's visibility is set to false. My code mostly works. My problem is when the dropdown extends past the parent canvas's boundaries (I don't mean the application window's boundaries). The dropdown appears fine but my button doesn't appear at all. I suspect it has something to do with z-order.
The dropdown displays fine when it extends past parent's boundaries. How do I do this for the button also? Thanks.
