draggable helper position - Can I call _getParentOffset()?
I have a draggable and droppable multi-level list. When you drag an
item over a closed parent item it expands (after a short delay) which
alters the position of the helper in relation to the mouse.
I've had a look into the draggable code and I can fix the problem by
calling _getParentOffset() to reset the offset.parent values in
_generatePosition which is called every time the mouse moves.
This seems like a bit of a hack and I was wondering if there was a way
to extend draggable to add a method to refresh the offset.parent
values?
