The Session and Speaker Catalogs have 3 main display styles:

1. Magazine
2. Promoted
3. General

You can select the style under Define Layout > Session Display

TIP: Magazine or Promoted styles are best for bringing attention to sessions you want attendees to notice first.

When working with Magazine or Promoted styles, you can select specific Sessions to show up at the top of the page under "Highlighted" and Promoted" headers.  These can be Set up in the in the Data area of the Session Catalog.
