Using jQuery UI draggable, how can I use a callback function on hover over a droppable object? -

i need append text cloned helper object when it's dragged on droppable object.

is there way trigger callback on hover on droppable object?

if understand correctly, want happen when draggable on droppable?

if so, use on event:

$('.iamdroppable').droppable({  over: function() {   //do here },  });
