Subpages and subsubpages
For more structure in your website, subpages can be defined that show up on the preceding page as a subpage, like the link "Subpages" which you see on this page. You have "Subpages of subpages"? No problem.
After you have defined a new page and its sections, you may "Add Section" Subpage on your preceding page and select this page as its subpage. Voila.
