You can dynamically disable and/or enable menu items using menu.itemDisable and menu.itemEnable.
A typical use of this feature is to disable a link to the current page in a navigation menu.
When a menu item is disabled, the user can not activate the item.
In plain HTML, you can disable a menu item by adding the "spmenuDisabled" class to the <li> tag.
To disable a menu item in a southprojects menu, you can call the menu.itemDisable(ID) method, where the menu is the variable for the southprojects Menu and the ID argument is the ID of the <li> item.
