16 * DraggableElement is a mixin class used to create elements that can be clicked
17 * and dragged by a mouse to a new position within a group. This class must be used
18 * in conjunction with OO.ui.mixin.DraggableGroupElement, which provides a container for
19 * the draggable elements.
25 * @param {Object} [config] Configuration options
26 * @cfg {jQuery} [$handle] The part of the element which can be used for dragging, defaults to the whole element
27 * @cfg {boolean} [draggable] The items are draggable. This can change with #toggleDraggable
28 * but the draggable state should be called from the DraggableGroupElement, which updates
