Topher

<p>This plugin provides a metabox on posts and pages listing existing WordPress Menus.  The end user is allowed to choose one and make it associated with the post or page via meta data.</p>
<p>Practically speaking, Featured Menus work exactly like Featured Images.  The Post or Page and Featured Menu are merely attached, and you must use a template tag or WordPress functions to render the Menu.</p>
<p>Please see <a href="https://wordpress.org/plugins/wp-featured-menus/other_notes/" rel="ugc">Other Notes</a> for examples.</p>
<h3>Usage</h3>
<p>Page or Post meta has a key called <code>_wp_featured_menu</code>.  A very simple way to render the menu is like this:</p>
<pre><code><?php
    $meta = get_post_custom();
    wp_nav_menu( array( 'menu' => $meta['_wp_featured_menu'][0] ) );
?>
</code></pre>
<p>A better way might be to test for the value first:</p>
<pre><code><?php
    $meta = get_post_custom();
    if ( is_numeric( $meta['_wp_featured_menu'][0] ) ) {
        wp_nav_menu( array( 'menu' => $meta['_wp_featured_menu'][0] ) );
    }
?>
</code></pre>

Provides a metabox on posts and pages listing existing WordPress Menus.

<p>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.</p>
<p>This plugin allows fine-grained permissions to be added to each individual menu item to display or not display the item based on the<br />
 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.</p>
<h4>Please Note</h4>
<p>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.</p>


Privilege Menu
