This is where you will add new Modules or edit existing Modules for the front end of your Joomla! web site. When you install Joomla!, 20 built-in Modules are available for use in the front end of your web site. Some Modules, like the Menu Module, are used in every Joomla! web site. Other Modules are optional.
Note that all Module Types have the same fields in the Details and Menu Assignment sections. These are documented in the Module Manager - New/Edit screen. Each Module Type has different Parameter fields. These are documented for each Module Type below.
Note that if you install one or more Joomla! Extensions, these Extensions may add new Module Types. In this case, your screen will show additional Types.
When the New button is pressed, the Module:[New] screen displays all of the Module Types available for the new Module. You can select the desired type either by clicking on the Module Name or by clicking on the Module's radio button and pressing the Next button on the toolbar. Note that you can cancel this action by pressing the Cancel button on the toolbar.
