Free form Drag and drop - advanced
Let's say I have bulit a free form drag and drop with three boxes that should be placed on three other boxes. If the student does it in the correct way he should get some kind of positive feedback when submitting. No problems so far. But if some of the boxes are placed in the wrong position I would like them to bouce back to there original position when hitting the Submit button. Two questions:
Is there an easy way to to this?
If not easily implemented, how can it be done anyhow?
