Turbolinks

To use the jQuery.mmenu plugin in combination with the Turbolinks framework, include the "turbolinks" wrapper .js file and add "turbolinks" 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.turbolinks.js"></script>
   <script>
      $(document).ready(function() {
         $(".navbar-collapse").mmenu({
            wrappers: ["turbolinks"]
         });
      });
   </script>

What it does

Using the "turbolinks" wrapper will enable the menu to be re-initiated after navigating to a new page "the turbolinks way".
