Sortables - how do they work?

Sortables - how do they work?


Hi jqueriers,
I'm working with a larger complex project where I'm trying to
incorporate multiple technologies. In particular, I'm trying to put an
O3D (http://code.google.com/apis/o3d/) object into a portlet (a la the
Sortable demo).
This fails in at least two ways; making the object hidden, or any
attempt to sort the object destroys the O3D client (or renders it
inoperable). Resizing the element is fine, though. So, I'm thinking
it may be possible to work around the problem.. if I can figure out
what bit of the drag/drop operation is killing the client.
Trying to read the source code is difficult - can someone tell me
briefly how the draggable/sortable objects work?
