Drag & Drop: Only continue, if all have been dropped on targets
Hello, we have the goal:
- The user has 8 drag items.
- He must drop all 8 onto the 5 targets, no matter if they're dropped correctly.
- Only then he is allowed to continue and "submit" his answer
- If not, pressing the submit button will display a reminder message (eg "Please drop all items before submitting")
We can't figure out how to do this yet.
We tried to use the states of the drag-items for this, doesn't work as the user might drag some back out of the targets and then they already have a dropped correct/incorrect state.
We tried to use the state "normal" of the drag items (items not dropped already) to display the reminder message and not submit, before all items aren't "normal" anymore. This seems not to work either. We hoped it would.
Next, we're trying around with SL360's intersection trigger...
Can anyone point us in the right direction and had a similar problem?
Thanks! We're close to a deadline and this has just come up.
See mockup in attachment for the setup.
