responsive toggle not working

[panaak]

hi,

just tried to install clean rails app with the latest foundation-rails 6.2.0.1

found out responsive toggle doesn't quite work.

.title-bar{"data-hide-for" => "medium", "data-responsive-toggle" => "example-menu"}
  %button.menu-icon{"data-toggle" => "", :type => "button"}
  .title-bar-title Menu
#example-menu.top-bar
  .top-bar-left
    %ul.dropdown.menu{"data-dropdown-menu" => ""}
      %li.menu-text Site Title
      %li.has-submenu
        %a{:href => "#"} One
        %ul.submenu.menu.vertical{"data-submenu" => ""}
          %li
            %a{:href => "#"} One
          %li
            %a{:href => "#"} Two
          %li
            %a{:href => "#"} Three
      %li
        %a{:href => "#"} Two
      %li
        %a{:href => "#"} Three
  .top-bar-right
    %ul.menu
      %li
        %input{:placeholder => "Search", :type => "search"}/
      %li
        %button.button{:type => "button"} Search

this is the example code from foundation website

the motion plugins are imported, the css files are in place. still the menu doesn't toggle and the menu-icon isn't displayed.

dont' know if it is a foundation's or foundation-rails'es problem..
