With Universe there are two different types of pages. There are "pages" and "subpages". Pages are what people see when they open the menu on your site. These can also be referred to as "tabs".
Subpages are located inside of pages/tabs and do not appear in the site menu. You can use subpages to create a blog post, digital magazine, or anything you can imagine! Subpages have the ability to scroll as one, or even allow you to swipe between them!
In the app, you will find subpages after you click on a main page. Using the free version of Universe, you can add as many subpages as you wish under the main home tab.
