This feature may be enabled for the module which allows items in that module to be 'grouped'. Each item may optionally be assigned only one category. Categories must be created before they can be selected, and are specific to a single module type. Modules with the category feature have special views which functionally group items by category in various ways (list headings, accordion sliding, tabs, etc...) Item categories are specific to a module in nature. The feature may be optionally enabled for the module. You may also choose to NOT sort the items by category, but have the category assigned (if you still wanted the list sorted by date, etc...) You may also assign the default label to use for 'un-categorized' items in place of 'Un-Categorized.'
