Template override for Joomla menu module
FUA can override the Joomla menu module and hide menu-items. See FUA configuration > 'menu access'.
However, in case this override conflicts with other installed extensions, you might need to use an override for Joomla's menu module in your template folder. Read more.
In case you do not have any template override for the Joomla menu module, you can download them here.
Installation instructions are included.
