How to connect to arbitary DOM elements using draggable in jQuery?

I've found a article that explains how to connect draggable elements to sortable ones:

But what I need is to connect draggable elements to arbitary DOM elements,

I need to do something when I drop it on some e开发者_开发问答lement.

But how know the element that the draggable is on when I drop it?

Create a droppable, and use $(this) inside the ondrop function you set to refer to the droppable, and then do the connection.

I believe that should do it, unless I misunderstand your problem.
