A Group is like a folder and it can contain other groups, or it can contain items. A Group can correspond to a directory, a section of a site, or a chapter in a book.

A Group is a collection of other groups or items. It is a "branch" node, so it doesn't have any content itself. Instead, it displays the description of its child nodes. These descriptions can be short or long. They will be displayed in the order in which they are displayed in Metawrite.
