Pages on a Contensive site are arranged first by section, then by a hierarchy controlled by a parent-child relationship.
The Contensive site can have any number of sections. An example of a section might be "About Us". Sections are what you would typically see in the main navigatation of a site.
Sections are displayed on a site in the Dynamic Menu Add-ons. When a menu is added to a template, you can decide which sections should be displayed on that menu.
When a visitor clicks on an entry in the menu, they go to the section. Since 'sections' do not display directly, the section contains the name of a page that will be displayed when the section is clicked. This page is called a Root Page, and is referred to as the root page of the section.
Child Pages and Parent Pages
All pages on a Contensive site can have Child Page, or 'sub-pages' under them. Think of the table of contents in a book. A child page is like the pages in a chapter. The difference is that any page in Contensive can have child pages. A page that has child pages, is called a Parent Page.
For instance, the About Us section of a website will have a Root Page that is where visitors will go when they click the "About Us" entry in the menu navigation. That page may have child pages, also visible as flyouts in the navigation, titled "Our Locations", and "Hours of Operation"
The About Us page discusses the company. This is the Root Page of the section. It has two child pages "Our Locations" and "Hours of Operation". It is therefor the "Parent Page" of those pages, as well as the "Root Page" for the two child pages.
