About the idea of using table ==> could be interresting, but IE have
some trouble with it !!!
About usability:
the problem is that while dragging, you should scroll to drop in the
fourth droppable, I personnaly think that people will don't have the
idea to do this even if there is a scrollbar, but I can be wrong.
So instead, I should use an automatic scrolling (perhaps on the onDrag
event fire by the droppabe/Draggable, and detect if your inside the
droppable area, and see where you are inside this droppable area, and
if you are at the bottom of the visible view, just change position to
scroll down automatically.
Just one thing, You could revert your change in scriptaculous, that
works too.
Another point while doing some test (I'm not what I consider a
javascript PRO, so try to learn while helping), with the
Position.includeScrollOffsets set to true, if you are on the Draggable
zone, and the Droppable is scrolled, you could still drop on the first
and second element ==> Funny. It seems that scriptaculous did not wait
to be on the Droppable area to test if mouse pointer is on a
element !!
