Preventing to drag objects after drop correct status
I suggest creating a trigger that shows another (blank) layer when all of the rectangles are in the "Drop Correct" state. Make sure "Prevent the user from clicking on the other layers" is checked.
I can't recall whether this was the default behavior, as it's been a while since I last used this drag-and-drop template. Normally, I would use another shape to prevent further dragging, or change the state of the draggable objects to Disabled once they are in the "Drop Correct" state, or use a similar technique.
Once the draggables are placed, their z-order seems to change.
In the example above, the draggables are clearly below the top-level blue rectangle until they're placed on a target, at which point they become above it. This wasn't something I was aware of, but it seems to be particular to this interaction type as I too have used invisible shapes before to block buttons on non-question slides.
Yes... this is a weird behaviour.
