<p>When writing or modifying a theme, the function wp_nav_menu() displays the contents of menus configured in your settings. If you have a lot of little menus the list can get hard to manage, so this plugin lets you group several menus under a single menu.</p>
<p>To use it, simply add a <code>submenu</code> parameter to the arguments of wp_nav_menu, like so:</p>
<pre><code>wp_nav_menu(array(
  'menu' => 'header',
  'submenu' => 'About Us'
));
</code></pre>


Subtitle Filter

Adds tha ability to show only a submenu with wp_nav_menu().

<h4>Features</h4>
<p>Caches the output of your menus. That’s it 😉</p>
<p>Specifically, it caches the output for every unique page. This allows the menus to retain the current/parent/child classes unlike most other menu caching plugins.</p>
<h4>Why should I use this plugin?</h4>
<p>If you want to cache your menu content obviously, but specifically if you want to cache your menu content <strong>and</strong> keep the current/parent/child page classes working. Most menu caching systems do not cater for keeping the various classes working, whereas this plugin does.</p>
<h4>Why shouldn’t I use this plugin?</h4>
<p>You should not use this plugin if you have a huge number of posts/pages on your site. The plugin caches each menu individually for each post. This can result in a huge number of cached menus on some sites, which could actually resulted in a slower site in those situations. It could also overload your object cache backend if it has insufficient memory to store them all.</p>
