Magento

To use the jQuery.mmenu plugin in a Magento project, include the "magento" wrapper .js file and add "magento" to the wrappers option.

<head>
   <script src="path/to/jquery.js"></script>
   <script src="path/to/jquery.mmenu.js"></script>
   <script src="path/to/jquery.mmenu.magento.js"></script>
   <script>
      $(document).ready(function() {
         $("#my-menu").mmenu({
            wrappers: ["magento"]
         });
      });
   </script>

What it does

Using the "magento" wrapper will sets the classNames.selected configuration option to the default classname used by Magento.
