Drag-and-drop interaction with active drop zone that is not evaluated

Hi FrançoisMichot​! 

Great to see Luciana has been helping you. Happy to jump in here!

Unfortunately, setting the Drop Target column lines to 'None' prevents the 'Snap to center' setting from functioning. This is the expected behavior for Storyline, as Drop Targets must be set for Drag-and-Drop options to apply to an object.

I do understand this limitation prevents you from implementing the partial scoring type of design you were after. I've shared this feedback with our product team! We'll be sure to notify you if we release a feature enhancement that helps.

As a workaround, I suggest splitting the interaction into two separate slides, then omitting one from the Results Slide. This will exclude it from being counted towards a learners final score. I'll also open the floor to our talented community who may be able to share more custom design suggestions with you!
