The SDL JavaScript Suite currently does not support the MenuManager and ChoiceSetManager. This will be addressed in a future release.
If you don't want to use the ScreenManager, you can do this manually using the Choice, CreateInteractionChoiceSet. You will need to create Choices, bundle them into CreateInteractionChoiceSets. As this is no longer a recommended course of action, we will leave it to you to figure out how to manually do it.
