Select Extensions → Module Manager from the drop-down menu on the back-end of your Joomla! installation.
The Module Manager is where you add and edit Joomla! Modules. In Joomla!, Modules are used to display things around the main page content. Some Modules, such as the Menu module ("mod_mainmenu"), are used in every Joomla! website. Other modules, such as Banners, "latest news", and "most read", are optional. Your website can have multiple instances of the same module. For example, all Joomla! menus are made using the "mod_mainmenu" module. So, if you have 5 menus, you will have 5 copies of the this module.
When you install Joomla!, 20 Modules are included. If you add extensions to your Joomla! installation, they may contribute additional modules.
The modules are sorted by the Position column by default but you can sort them by any column, just click the column header.
Position of a New Module
A newly installed module is disabled by default and is the last one in the left module position. This way you can easily find it and move it to the desired place.
Support Old Modules in Legacy Mode
Some old 1.0.x modules support Joomla! 1.5 in Legacy Mode. To be able to install such extensions please open the Plugin Manager screen from the Extensions menu and enable plugin System - Legacy as it is disabled by the default.
You can view the installed modules list on the Modules tab of the Extension Manager by clicking the Extensions -> Install/Uninstall menu item. You can remove them in this screen as well.
In Joomla! 1.5 the Module Manager was moved to the Extensions menu and got a tabbed interface for displaying the site and administrator modules. The below changes are related to both clients:
One module can be enabled/disabled by clicking the icon in the Enabled column. The enabled modules are marked with a green tick while the disabled ones are marked with a red X. When you want to enable/disable several modules, select their checkboxes and click the appropriate toolbar button.
When you want to create a copy of one or more modules select the checkbox(es) and click the Copy toolbar button. An information message will be displayed and you will find the module(s) with the name(s) "Copy of ..." inserted into the module name(s). The copies will have a disabled status.
When you want to delete one or more unnecessary modules select the checkbox(es) and click the Delete toolbar button. An information message will be displayed and the module(s) will be removed from the list.
You can create another instance of an installed or custom module using the New toolbar button. When you click it, the Module: [New] screen will be loaded. Select the desired module and click the Next toolbar button or simply click the module type.
You can enter the title, customize the details and the parameters and assign it to a menu in the loaded Module: [Edit] screen.
The four drop down lists make you easier to narrow the list of your choice, or you can enter a string in the Filter field and click the Go button to find the matching modules in the list.
The items can be moved up/down by clicking the arrows in the list, or they can be renumbered by entering a value in the field next to the arrow. In this case the order should be saved by clicking the floppy icon.
The access for a module can be changed simply by clicking the Public/Registered/Special value in the Access Level column.
