Sometimes you may have a lot of admin menu items based on your WordPress installation, with this plugin you only need to type a few letters of the item name that you look and voila! Using a custom jQuery expression that extends the “contains” to a case insensitive the plugin add a class ‘filtered’ for non-match elements and perform actions based on 2 simple rules:

2. For child menu item matching the item keeps highlighted and their parent visible, keeping the rule #1 for the rest of parent menu items.
