    .nav-wrapper
      %a.brand-logo{:href => "#!"}
        %i.material-icons> cloud
        Logo
      %ul.right.hide-on-med-and-down
         %li
            %a{:href => "sass.html"}
              %i.material-icons search
         %li
           %a{:href => "badges.html"}
             %i.material-icons view_module
         %li
           %a{:href => "collapsible.html"}
             %i.material-icons refresh
         %li
