A modal page does not allow the end user to select the underlying page (page is greyed out), whereas, they can select the underlying page with non-modal pages. These new modal and non-modal page types have the same declarative capabilities as normal pages with respect to defining regions, processes, branches, and so forth.
... Navigation ListsNavigation lists are a modern alternative to tabs. They allow to render a menu similar to the drop-menu in the APEX Builder, at a designated position on the page and provide navigation links to other pages in the application. Themes support either traditional tabs or navigation lists. Once an application is created using a theme that supports navigation lists, all wizards will show options appropriate for this type of navigation instead of the traditional tab options shown.
