Every WikiGroup can have GroupHeader and GroupFooter pages that contain markup that should be included at the beginning or end of each page within the group. This feature is useful for:

• adding a disclaimer or heading to all of the pages of a group
• defining custom WikiStyles that may be used for all pages in a group
• replacing the default headers and/or footers for pages in a group (e.g., using (:noheader:) and or (:nofooter:) -- see PageDirectives).

To create a group header, just create a new page called YourGroup.GroupHeader. Group headers allow authors to create groups with custom headers and footers without having to coordinate with a wiki administrator.

The default GroupHeader or GroupFooter can be suppressed on an individual page (such as a group's HomePage) by using the (:nogroupheader:) and (:nogroupfooter:) markups on that page.

If a generic GroupHeader is used in one wikigroup (say, the Site wikigroup), then the code can be easily duplicated in the GroupHeader of any other group by using (:include Site.GroupHeader:). See IncludeOtherPages.

If you want a header or footer to appear when you print a page (action print), simply create a page called YourGroup.GroupPrintHeader or YourGroup.GroupPrintFooter and fill it with your markup.

You can also set the variable $GroupPrintHeaderFmt and $GroupPrintFooterFmt in the same way as $GroupHeaderFmt and GroupFooterFmt in order to change the header used when action=print.
