title: Drag-Drop elements between parent frame and child iframe
body: <p>I am trying to drag-drop elements between parent frame and iframe using jQuery.
  I have a panel in parent frame which contains some draggable items which can be dropped on the child frame. I tried to search a lot but couldn't find much...</p>
  
  <p>I tried to work around it by appending the element inside the child frame and then trying to trigger draggable on the newly inserted element programmatically, but I got stuck there as well. Couldn't find the proper way to trigger the drag function. (The draggable element has a helper. When I trigger drag by triggering "mousedown.draggable" the position on the ui-draggable element changes but I cannot see the helper.</p>
  
  <p>Thanks!!</p>
