jQuery UI Interaction : Droppable

Using jQuery droppable plug-in , you can  make selected elements droppable (meaning they accept being dropped on by draggables).

All callbacks receive two arguments: The original browser event and a prepared ui object, view below for a documentation of this object (if you name your second argument 'ui'):

  • ui.draggable - current draggable element, a jQuery object.
  • ui.helper - current draggable helper, a jQuery object
  • ui.position - current position of the draggable helper { top: , left: }
  • ui.offset - current absolute position of the draggable helper { top: , left: }
