Hide Menu Item from Registered and Special

Refer to this link if you want to clean out a front-end admin interface with your website's style.  The following is from http://forum.joomla.org/viewtopic.php?f=32&t=252258&start=0 at this date/time.

Can't simply hide an item but can hide a menu (of course the menu could have been created with just one item with no title and positioned at the bottom of another menu; this would look like it was all part of one menu).

This cannot be done by joomla administration but can be done by template code, you can have a module position in the template that is set to only show when the visitor is not logged in e.g. Code:

<?php if ( !$my->id ) {?> 
     <div id="topmod"><?php mosLoadModules ( 'top', -2 ); ?> </div>
<?php } ?>

Joomla extension disable menu link for registered users but not for public
