  13  * @class Roo.dd.DDTarget
  14  * A DragDrop implementation that does not move, but can be a drop
  15  * target.  You would get the same result by simply omitting implementation
  16  * for the event callbacks, but this way we reduce the processing cost of the
  17  * event listener and the callbacks.
  18  * @extends Roo.dd.DragDrop
  19  * @constructor
  20  * @param {String} id the id of the element that is a drop target
  21  * @param {String} sGroup the group of related DragDrop objects
  22  * @param {object} config an object containing configurable attributes

  24  *                 DragDrop:
