ruby-on-rails – 无论如何使用Active Admin添加其他级别的菜单

通知ActiveAdmin我们将使用标头本身.为此,在config / initializers / active_admin.rb文件中添加以下行：

config.view_factory.header = CustomAdminHeader
config.register_stylesheet 'new_menu.css'

创建一个名为CustomAdminHeader的类,该类将包含将覆盖构造菜单的代码.您可以在app / admin中创建此类,并将该文件命名为custom_admin_header.rb.并添加此代码以创建新菜单：

class CustomAdminHeader < ActiveAdmin::Views::Header
  include Rails.application.routes.url_helpers

  def build(namespace,menu)
    div :id => 'tabs' do
      # Add one item without son.
      ul do
        # Replace route_destination_path for the route you want to follow when you receive the item click.
        li { link_to 'Item without son',route_destination_path }
      end

      # Add one item with one son.
      ul do
        li do
          text_node link_to("Parent with 1 child","#")
          ul do
            li { link_to 'Son without child',route_destination_path }
            # If you want to add more children,including more LIs here.
          end
        end
      end

      # Adds a menu item with one son and one grandson.
      ul do
        li do
          text_node link_to("Grandmother with 1 child","#")
          ul do
            li do
              text_node link_to("Parent with 1 child",route_destination_path)
              ul do
                li { link_to 'Grandson without child',route_destination_path }
                # If you want to add more grandchildren,including more LIs here.
              end
            end
          end
        end
      end

    super(namespace,menu)
  end
end

菜单的结构将由此类创建,因此不应显示文件夹app / admin中包含的类中使用的菜单设置.为此,您需要在所有类中添加以下代码：

menu false

最后,您需要创建一个名为new_menu.css的CSS文件,并为新菜单添加CSS.
