## Description

Page groups define sections of the display page tree. A page group consists of an internal name, a display name, and a category. The internal name can be used to locate a registered page group. The category is used to sort the page groups.

While RBDisplayPageGroup is a subclass of RBDisplayPage, by default page groups are never selectable so they have no content.
