Drag and Drop - making submit button appear only when all drag items are on an answer option

Hi Annie,

Not the exact solution you want, but when I have more complex drag and drops and come up with issues like this, I sometimes add a RESET button so that the learner can reset everything to the original starting point if they want to change their answers. So, when the learner drops a drag onto a target, I trigger the drag to item to turn to Disabled. Then, once all are disabled, the Validate button can turn to Normal. and the Reset button is there all the time if the learner wants to start over (it's usually a Jump to his slide trigger, with the slide set to Reset to initial state). Not ideal if you have many items, but might work with only 5?

For me, I feel this gives me more control as there is too much that can go wrong with users dragging objects all over the screen.

Still I'll think a bit more about this and let you know if I come up with something better, and others may have a better solution.
