If you have a lot of items on your Registration Form and want to break up content into smaller sections, you may do so by defining Registration Menus. Also, an advantage of multiple screens is to prevent a long screen form from an end user's experience, as well, certain logic may be applied so that certain questions will appear conditionally based on previous screen responses.
For example, your registration types could be on one screen, the next screen could contain options to purchase social event tickets. Another screen could be a donation screen or a Questionnaire on Dietary Restrictions.
Now in your Registration Fields, you may set the Screen field to Social Activities so your fields will appear on the Social Activities screen.
