Drag and drop - answer incorrect help
I have been working to create a drag and drop (attached) and have successfully completed most elements, however there is an issue with incorrect answers!
I've set it up so that when a text box is dragged to the correct answer, it disappears. However, when it is dragged to the incorrect answer, it snaps back to the beginning. On top of this, I've ticked the setting to reveal one answer at a time.
When an answer is dropped incorrectly, it snaps back to the beginning and another answer is also revealed, causing them to overlay and be unreadable.
Can anyone suggest the best way to resolve this?
