Class \Prado\Web\UI\JuiControls\TJuiDroppable
TJuiDroppable class.
TJuiDroppable is an extension to TActivePanel based on jQuery-UI's Droppable interaction. When a TJuiDraggable is dropped over a TJuiDroppable panel, the \Prado\Web\UI\JuiControls\onDrop event will be triggered. The event hanler will receive a TJuiEventParameter object containing a reference to the dropped control in the DraggableControl property.
