Using this plugin you can use WordPress
Conditional Tags to enable or disable menu items on the front-end. It works like 'Widget Logic' but for menu items.
Usage
You must insert conditional tags in the "Visibility" box in the menu item options form. You can use any PHP or WordPress functions to build crazy conditions and logics for menu items. For example, to hide the menu item on homepage you can set the visibility to:
! is_home()
Show the menu only to logged-in users:
is_user_logged_in()
Show the menu only to guest visitors:
! is_user_logged_in()
To show the menu item based on
user capability:
current_user_can( 'manage_options' )
