Ever get tired of seeing the same menu options you literally never use? Or setting up a WordPress install for a client, and want to get rid of the stuff they don’t use, or would screw up if they could?
Us too. So we made this handy little plugin that gives you little checkboxes next to each menu item and sub-menu item, even for other plugins! Just uncheck the items you don’t want to see anymore, and they’re gone! When you need them again, just recheck and they’re back! No editing core files, and being over-written upon upgrade.

Simple Admin Menu Editor

Easily and Simply show and hide what is in your admin nav. That's it.

Uses the native <a href="https://codex.wordpress.org/Function_Reference/wp_nav_menu" rel="nofollow ugc">wp_nav_menu()</a>. Add parameters to the wp_nav_menu() to enable functionality. 
Also, ships with one-click delete menu-items in the WordPress admin. Turned off or on using the screen-options. Sweet.
Examples
This will get the first sub-menu from the active branch and 2 levels beyond (menu + sub-menu + sub-menu):
<pre><code>wp_nav_menu( array(
 'level' => 2,
 'depth' => 3
));
</code></pre>
Show the current branch only:
<pre><code>wp_nav_menu( array(
 'level' => 1
));
</code></pre>
Aimed on simple use in various use cases:
<pre><code>// display first level in the header
wp_nav_menu( array(
 'depth' => 1
));

// display first sub-menu from the current branch somewhere else
wp_nav_menu( array(
 'depth' => 2,
 'level' => 2
));
</code></pre>
Another feature is it’s control over the css classes that are given to a menu-item. You might be faced with css selectors 
which you cannot change. The ‘codepress_menu_filter_classes’ filter can be used in your functions.php to set the class property:
<pre><code>/**
 * Change the classes of a menu item
 *
 * @param array $classes List current classes
 * @param object $item Current menu item
 * @param array $items Current list of items (per level)
 * @param integer $k Key of the current item in $items
 */
function codepress_menu_item_classes( $classes, $item, $items, $k ) {
 // mark the first item
 if ( reset( $items ) == $items[ $k ] )
 $classes[] = 'first';

 // mark the last item
 if ( end( $items ) == $items[ $k ] )
 $classes[] = 'last';

 // map the WordPress default 'current-menu-item' class to 'active'
 if ( in_array( 'current-menu-item', $classes ) )
 $classes[] = 'active';

 return $classes;
}
add_filter( 'codepress_menu_item_classes', 'codepress_menu_item_classes', 10, 4 );
</code></pre>
Simple Menu Delete
It ships with one-click delete menu-items within WordPress. 
This functionality was integrated from our Simple Menu Delete plugin and enhanced a bit:
<ul>
<li>Turned off or on using the screen-options.</li>
<li>Display is more in line with WordPress’s way of delete-links.</li>
<li>Works exactly the same now as the nested delete-link which is a click further inside the menu item.</li>
</ul>

Codepress Menu

Allows you to display a sub-menu, it's depth from there on and gives you control over the menu-item classes.
