Symbolic Drag and Drop instead of showing Element

Hi all,

I apologize if this is not the right place to post this.

I am implementing a sortable list and I see there is the option of
ghosting (temporarily leaving behind a copy until the drop is complete).
This is, however, not what I want.

What I would like to do is have a symbolic drag representation rather
than showing the actual element contents while dragging. i.e. show a
transparent rectangle or some other element during the drag but show the
actual element that was dragged when the item is dropped (whew!). This
is implemented in the Yahoo! library via the DDProxy class.

I’m sure it’s possible to extend to do this, I’m just
not sure how. Could anyone please give me a nudge in the right
