The Menu Manager controls the framework, or container of the menu(s) in Joomla!. The actual menu functionality and appearance of a menu is created automatically by Joomla! by triggering a new instance of [mainmenu] when a menu is first created. It is this, together with the menu item(s) selected, that creates the finished menu.
New in Joomla! 1.5:
You can open the Menu Manager by clicking its quick icon in the Control Panel after logging in the administration back-end or you can access it from the Menus -> Menu Manager menu item.
Using the Menu Manager you can create your menus containing your menu items. This screen summarizes the details of the available menus by displaying the number of published/unpublished, trashed menus and the number of the modules.
You can create a new menu by clicking the New toolbar button. You can edit an existing one by selecting it and clicking the Edit button on the toolbar or by clicking its title. When you want to create a copy of a menu just select it and click the Copy toolbar button and the following screen will be displayed:
As you see, the copied menu and its menu items are also listed on this screen.
You should fill in two fields:
Click the Copy toolbar button to complete the process. If you decide not to create the copy of the menu, then click the Cancel button on the toolbar.
You can remove an unnecessary menu by selecting it and clicking the Delete toolbar button and the following screen will be loaded:
The details are summarized on this screen, so it easier for you to make your decision. Click the Delete toolbar button to complete the process. If you decide not to remove the copy of the menu, then click the Cancel button on the toolbar.
It is expedient to give a descriptive title for new menus because later you will see it in the Backend Menus menu. It is a good idea to fill in the Description field where you can give some information about the menu. As well it is recommended to enter a short title in the Module title field, you can identify the module with this name in the Module Manager that belongs to the respective menu.
Create a copy in the Module Manager
Though you can create a copy of a selected menu by clicking the Copy toolbar button, you can make another instance in the Module Manager easier.
Creating a new menu
When you want to create a new menu, in the Unique Name field use only english alphanumeric characters without space to identify a unique name. It is a good idea using only a-z, 0-9 and underscore (_) characters. Please read the tooltips as well.
If you don't enter a Module title, no module will be created, and the menu cannot be displayed in the front end. However you can later use the Module Manager to create a new mod_mainmenu module, and assign it to the menu.
Deleting an existing menu
If you delete an existing menu, do not forget that all the menu items of the respective menu will be also deleted.
Main Menu cannot be deleted
Main Menu is your default menu and cannot be deleted. That is why it is marked with an asterisk (*) in the Menus menu. It can be unpublished however, if you wish to do so.
The menu items belonging to a specific menu listed in the Menu Item Manager can be accessed by clicking the icon in the Menu Item(s) column of the Menu Manager.
