Well,
I have implemented the lazy Draggable onmousedown, but it is not faster.
It seems that:
- Calling Droppables.add(li,{greedy:false, onHover:Ajax.Tree._onHover,
onDrop:Ajax.Tree._onDrop});
- Dragging is slow
Is very slow ...
Any Idea to did that with scriptaculous ?
http://peter.michaux.ca/article/15 seems complicated .... ?
