jQuery UI sortable scroll helper element offset Firefox issue

Question

I have a problem with a jQuery UI 1.7.2 sortable list in Firefox 3.6, IE7-8 work fine. When I\'m scrolled down a bit, the helper element seems to have an offset of the same

Answer 1

Setting overflow: auto makes Firefox start the drag with the element under the pointer, but it also prevents autoscroll from working properly. You can see that right in the jQuery Sortable example, if you make the window small enough that scrolling is needed.

I had overflow: scroll on the html tag, but even removing that and (I think) all the relative containing elements didn't totally solve the problem (meaning the drag starts correctly and autoscroll works). I also tried a mozilla-sniffing patch to _findRelativeOffset (I think that was it), but it didn't help.

What did help for my use case was just dragging with a clone (helper: 'clone' in the draggable constructor). To make it look like the clone wasn't there, I added start and stop methods that just set the visibilty to hidden and then back.

I would have commented above, but I don't have the points yet.
