FuzzGuard

This plugin allows you to display menu items based on if a user is logged in, logged out or based on the role you have given the user.
This plugin allows fine-grained permissions to be added to each individual menu item to display or not display the item based on the 
 users logged in/logged out status or the role assigned to the user. This solves the problem of having to modify theme functions.php files to add in menu restrictions. The changes in functions.php is often overwritten by a theme update. This plugin removes that worry, as you can update the theme, independent of the plugin.
<h4>Please Note</h4>
This plugin uses a modified version of the Nav Menu Walker class. This means any other plugins that utilize their own custom Nav Menu Walker class, can and will conflict with this plugin. WordPress developers have support for proper custom hooks in this area of the Admin Menu slated for v4.8 release. Please see FAQ item “I cannot see the options for Privilege Menu under menu items in the Admin Panel?” for more information.

Menu Tamer adds collapse/expand links to nav menu items in the WordPress admin interface. If you have a large navigation menu, managing it can become a frustrating task due to the sheer size it takes up. Menu Tamer lets you collapse any branch of a nav menu to get it out of the way.
Menu Tamer has been tested in the latest versions of Chrome, Safari, and Firefox, as well as Internet Explorer 7, 8, and 9 (understandably, it is much slower in IE, but it works).
