[jQuery] Can a list be sortable and droppable at the same time (with Interface)?

[real]

Hi,

I have an unordered list that needs to be sortable, but also
droppable. I'm using the Interface plugin, but whenever I make one UL
both droppable and sortable, it doesn't function properly.

Either that, or is there a way to have the same functionality as the
onDrop callback (for droppables), but on a sortable? The onStop
callback (for sortables) doesn't cut it.

Thanks.
