I am planning to have three questions per slide. Currently, the question disappears from the slide when as answered. Is there a way to keep the questions visible until “next” button is selected?
Can you clarify?
It sounds like you might be referring to the one-at-a-time interaction, in which case you will see one question per page and the pages will automatically advance (for certain question types).
You may want to review the different interaction options:
Hope this helps!
