Modules

Small display Items with content that can be displayed anywhere that your template permits. Modules are, generally, very easy to install in the Administrator (Back-end). The Joomla! Core includes: Main Menu, Top Menu, Template Chooser, Polls, Newsflash,and Hit Counter amongst others. Members of the Joomla! Community also produce Joomla! Modules on a continuous basis. They are freely available on Joomla! Extensions Portal for download. An example of a Module PHP code is <?php mosLoadModules ( 'module position' ); ?>. See also: Module Position.

Module Position

Names for the placement of Modules within a template. There are 27 pre-named positions, e.g. left, right, top, bottom and 23 author-defined positions. Module positions are not confined by their name. Thus, the left Module position, coded as <?php mosLoadModules ( 'left' ); ?> may be placed anywhere in the template. See also: Modules.
