Make it possible to return other elements

Make it possible to return other elements

Hi, I am trying to make a jquery ui widget that can be used together with other things, example of what I want to do:
$('#droppable').mywidget().droppable({drop: function() { alert('Something dropped"); });

My widget:
$.widget('ui.mywidget', { _init: function() { $('<div></div>').insertAfter($(this.element)); } });

Unfortunatly, this only makes the original #droppable droppable and not what was inserted extra. What would be nice is if the widget could return what elements should be continued to be selected (and default to current behaviour). Does this make any sense?
