<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>
