jQuery Draggables and Droppables Positioning

I'm using jquery UI and jQuery draggable, all my draggables use jquery clone helper and appends the draggable to droppable.

Here is my code

 $('#squeezePage #droppable').droppable({
  tolerance: 'fit',
  accept: '#squeezeWidgets .squeezeWidget',
  drop: function(event, ui) {
   var dropElem = ui.draggable.html();

   var clone = $(dropElem).clone();

   clone.css('position', 'absolute');
   clone.css('top', ui.absolutePosition.top);
   clone.css('left', ui.absolutePosition.left);

   $(this).append(clone);

   $(this).find('.top').remove();
   $(this).find('.widgetContent').slideDown('fast');

   $(this).find('.widgetContent').draggable({
    containment: '#squeezePage #droppable',
    cursor: 'crosshair',
    grid: [20, 20],
    scroll: true,
    snap: true,
    snapMode: 'outer',
    refreshPositions: true
   });

   $(this).find('.widgetContent').resizable({
    maxWidth: 560,
    minHeight: 60,
    minWidth: 180,
    grid: 20,
   });
  }
 });

I'm setting the position of the clone with .css('top', ui.absolutePosition.top); and css('left', ui.absolutePosition.left); but the position is relative to the BODY.

The position is not relative to the droppable which makes the draggable drop to random places. Overall, the droppable and draggable integration is not tight开发者_如何学Go. I want to make it smoother.

I'm getting the offset of body and subtracting it from the offset of the widget clone.

clone.css('top', ui.position.top - droppableOffset.top);
clone.css('left', ui.position.left - droppableOffset.left);

It works!
