efficient way of dragging tons of elements in javascript
I am working on a web-page that has about 5000 objects each of which needs to be able to be dragged. I don't want to use jQueryUI draggable because it would attach mousedown/move/up events to each of 5000 elements which is a lot of overhead. I am rather looking for a lib that can manage dragging via the events of the parent object leaving the dragged (child) objects as minimal as possible.
