<pre><code>navigation.html.haml

.container-fluid
  .navbar-header
    %button.navbar-toggle.collapsed{ type: 'button', data: { toggle: 'collapse', target: '#secondary-navigation' } }
      %span.sr-only= t('admin.toggle_navigation')
      %span.icon-bar
      %span.icon-bar
      %span.icon-bar
    %a.navbar-brand.pjax{href: dashboard_path}
      / = _get_plugin_name[0] || 'Rails'
      = "myapp"
      / %small= _get_plugin_name[1] || 'Admin'
  .collapse.navbar-collapse#secondary-navigation
    = render partial: 'layouts/rails_admin/secondary_navigation'
