Catalyst has been constructed with an assortment of 25 module positions allowing for one of the most versatile designs ever. These module positions are fully collapsible meaning that if there are no modules published in particular area, that module area will not be shown. This provides you with the maximum amount of flexibility possible.

Catalyst includes built in style and implementation for the extra module positions "user10", "user11", "user12", "advert4" and "search". These module positions are not defined in a default Joomla install.

You can use these additional module positions by going to "Admin > Extensions > Module Manager > A Module" in here, double click the Positions field and insert the non-standard modular positions.
