css - Bootstrap 3 可折叠不工作

Question

我有一个带有 bootstrap 3 的 Rails 应用程序，菜单没有折叠。此外，当我调整大小时，折叠菜单有时会出现三个栏，但正常的菜单项仍然在那里，只是紧挨着它挤在一起。这是 haml 提前致谢。

%nav.navbar.navbar-inverse{role: 'navigation' }
    %div.container-fluid
      %div.navbar-header
        %button.navbar-toggle{type: 'button', 'data-toggle' => 'collapse', id: 'menu-toggler', 'data-target' => '.navbar-collapse'}
          %span.icon-bar
          %span.icon-bar
          %span.icon-bar
        = link_to (image_tag 'logo.png', class: 'logo'), root_path, class: 'navbar-brand', 'data-no-turbolink' => true
      %div.collapse.navbar-collapse
        %ul.nav.navbar-nav.navbar-right
          %li.active= link_to '<i class="icon-dashboard"></i> Dashboard'.html_safe, root_path, 'data-no-turbolink' => true
          %li= link_to '<i class="icon-signout"></i> Logout'.html_safe, destroy_user_session_path, method: :delete
          %li= link_to '<i class="icon-envelope"></i> Contact Us'.html_safe, new_contact_request_path
          %li.dropdown
            %a.dropdown-toggle{href: '#', 'data-toggle' => 'dropdown'}
              %i.icon-gears
              Profile
              %b.caret
            %ul.dropdown-menu
              %li= link_to 'Manage email addresses', emails_path
              %li= link_to 'Edit Account', edit_user_registration_path
              %li= link_to 'Setup Wizard', setup_wizard_home_index_path
              %li= link_to 'Cancel Account', cancel_account_home_index_path

您是否将 //= require bootstrap 添加到您的 javascript list 中？
