I think Lieve may be referring to the feature in the Infosemantics Drag and Drop Lite question widget where you can nominate an object on the slide (e.g. a caption or image icon) that only appears in Quiz Review mode for that question slide.
In Quiz Review the user is normally shown the final position where they placed their drag objects. To see what the correct answer was, the user can mouses over the review object and the drag objects will all animate and move to their correct answer locations. Mouse away from the review object and the drag objects return to the positions they were placed by the user's answer.
This may be a little different to what you wanted because you did not mention you wanted this to happen in Review Mode but when your user failed all allowed attempts.
