Apply penalties for elements dropped in the wrong drop zones. This must be enabled when the same element(s) are able to be dropped into multiple drop zones, or if there is only one drop-zone. If this is not enabled, learners may match all items to all drop-zones and always receive a full score.
If this field is set, it will override opacity set on all draggable elements. This should be a number between 0 and 100, where 0 means full transparency and 100 means no transparency
