Im having problems to have a sortable under other sortable. In Firefox/Chrome/Safari works great you can sort items inside their ul. But on IE (Any version) I get a display error when sorting Subs.

I have an example here you can try. Add one or more "Parent" and then add Subs under Parent. Try to sort those subs under that Parent and you will get a misbehavior ​http://blunk.com.ar/dev/sort/

In the .draggable() widget, the "helper" object is what visually moves around the screen while dragging. The default behavior has the draggable element itself serve as the helper object.

When specifying a helper function, I sometimes want to mimic this default condition, where the helper is the draggable. But returning the draggable element (as a jQuery object) doesn't do this, that just makes the helper invisible.

In this ​jsfiddle demo, the first img drags, but the second doesn't seem to budge. The dragging is going on however, a stop function would get called.

Using jQuery 1.10.2, UI 1.10.3 in my application and seeing this. The jsfiddle demo uses 1.9.1/1.9.2

When setting the source for autocomplete as an external URL, adding get elements is not possible. For example: This works:

$( "#id" ).autocomplete({source: "file.php"});

This doesn't work:

$( "#id" ).autocomplete({source: "file.php?a=1"});

I think the reason for that is that it results into using this url: file.php?a=1?term=... in stead of file.php?a=1&term=...
