I'm making a tasklist. I want it to be sortable, but ui.sortable interferes with my goals (I want tasks to be droppable to one another as well, to create subtasks).

So I've programmed something quite nice and similar with draggable and droppable. To make it like ui.sortable, I'm adding in droppable spacers that will expand on dragover and that will (in future) handle when user drops a task on them.

I'm having trouble with the out event (of ui.droppable on these spaces). I added an animate to make them gently shrink back to minimal size when the draggable is no longer over them. But though I set the speed at 1000 ms, it seems to jump to this minimal size immediately.

I have a hunch that the aria-disabled class is part of the problem. But what the heck is aria?

Regards!
