Drag and Drop locking
I'm creating a free form drag and drop and there are two statements that the user has to drag into the box that is most appropriate to them and they must put a statement into both boxes. However one statement may be relevant in both boxes. Therefore I have created 4 drag objects, stacking them on top of one another to give the impression that there is only one of each statement. This is where my problem lies, I want to be able to stop the drag and drop once two statements have been placed into the relevant box(es). Is this possible? Has anyone found a way to do this?
