Group A group is a way to organize the content within Pmwiki. A group contains pages which are related in some way to the name of the group. For example, on this site Main, Cookbook, Site and PmWiki are all groups. You will find all Recipes in the Cookbook group. A group can be thought of as a Major Topic that contains pages and each page contains information about a related topic. In PmWiki, a group only contains one level of hierarchy. Despite this limitation, it is possible to have content that is hierarchical in nature by clever structuring of Menus, Trails, Categories and Pagelists. If one is building a PmWiki site about Animals, one possible way to have groups is Animals/ under which would be Classification, Origin, Extinct etc., Vertebrates/ under which would be Fish, Amphibians, Reptiles, Mammals and Mammals/ under which there would be pages Marsupials, Primates, Rodents etc.
