By hiding and showing containers you control what your participants see at a given time. The view is updated in real time, so it's possible to use this feature as a facilitation tool; show and hide content as you please to make the workflow easier to follow and to not make the participants overwhelmed or distracted with too much information available at once.
How to hide container:
Open the Action menu > Edit page layout > click the container's ...-menu > choose Hide > Click Close edit mode
How to show container:
Open the Action menu > Edit page layout > click the container's ...-menu > choose Show > Click Close edit mode
