Catalog groups
Catalog groups are generic groupings of online catalog entries within a catalog. A catalog group may contain more than one catalog group or catalog entries. You can associate catalog groups with any number of catalogs. For example, the "Men's Pants" catalog group can be associated to the "Summer", "Winter" and "Spring" catalogs.
Although catalog groups can include catalog entries for any purpose, the main intent of catalog groups is for catalog partitioning purposes. Catalog groups also determine the navigational hierarchy of an online catalog.
