### Default value
> 0

Setting this to 1 indicates that this object is a valid site on which to drop other objects. While dragging, mouse_drop_cursor of the object being dragged will become active in this case. Note that this is a purely visual effect. It does not control what the user may do with the mouse. You control the real behavior with the associated procedures.
