Bootstrap 导航栏 rails gem glypicon

Question

我刚刚添加了 gem rails-bootstrap-navbar to my rails project and I would like to be able to add a glyphicon in front of my dropdown menu, there is no problem to do it with a menu-item but for the dropdown itself, there is no example in the documentation。由于下拉列表已经是一个块，我不知道如何向其添加跨度。

= navbar fixed: :top do
  = navbar_header brand: 'My great app', brand_link: '/home'
  = navbar_collapse do
    = navbar_group class: 'foo', id: 'menu' do
      = navbar_text 'Pick an option:'
      = navbar_item "Home", '/'
      = navbar_item "About Us", '/about-us'
      = navbar_item '/contact' do
        %span.glyphicon.glyphicon-hand-right
        Contact Us!
      = navbar_dropdown "I want an icon too :-(" do
        = navbar_item '/contact' do
        %span.glyphicon.glyphicon-hand-right
        I can easily have an icon :-)
        - if true # check if user is admin, maybe like "if current_user.try(:admin?)"
          = navbar_dropdown_divider
          = navbar_item "Admin Dashboard", '/admin'
          = navbar_item "Users", '/admin/users'
    = navbar_group align: 'right' do
      - if true # check if user is logged in, maybe like "if current_user.present?"
        = navbar_item "Log Out", '/logout'
      - else
        = navbar_item "Log In", '/login'

我想要更改的确切部分

          = navbar_dropdown "I want an icon too :-(" do
            = navbar_item '/contact' do
            %span.glyphicon.glyphicon-hand-right
            I can easily have an icon :-)

你试着像下面那样做

= navbar_item "<span class='glyphicon glyphicon-user'></span> Users".html_safe, '/admin/users'
