RefineryCMS 2.1.0 and Zurb 4 Top menu with dropdown navigation

问题

I'm trying to use Zurb foundation to style an app built with the latest version of refinery. I began by following this guide

http://blog.flatironschool.com/post/54511602806/build-a-blog-based-site-with-refinerycms

but the latest version of refinery uses "menu-presenter" to layout the menu.

I have got this far:

module ApplicationHelper


   def zurb_menu
      menu_items = Refinery::Menu.new(Refinery::Page.in_menu)

      presenter = Refinery::Pages::MenuPresenter.new(menu_items, self)
      presenter.css = "top-bar-section"
      presenter.dom_id = nil
      presenter.menu_tag = :section
      presenter.list_tag = "ul class='left'"
      presenter
   end
end

This sort of works, However the elements aren't quite right and the main problem is that the I don't know how or where to add the dropdown class to make the child elements dropdown. With the code above the child elements are just expanded all the time.

Thanks for your help

回答1:

instead of in_menu if you use fast_menu, then you will be able to reorder pages. menu_pages works, but you it will not render pages in the same order as they are in admin. hope this helps someone.

menu_items = Refinery::Menu.new(Refinery::Page.menu_pages)

menu_items = Refinery::Menu.new(Refinery::Page.fast_menu)

This is my version... Tested; and it works for me at least.

I used the code for Bootstrap I found on another question (link in the comments above). But instead of replacing the entire menu presenter I override only the methods we need for this.

Create a Zurb menu presenter file:

app/presenters/refinery/pages/zurb_menu_presenter.rb

module Refinery
  module Pages
    class ZurbMenuPresenter < MenuPresenter

    config_accessor :list_dropdown_css, :list_item_dropdown_css, :list_first_css

    MenuPresenter.menu_tag = :section
    MenuPresenter.css = "top-bar-section"
    self.list_dropdown_css = "dropdown"
    self.list_item_dropdown_css = "has-dropdown"
    self.list_first_css = nil

      def render_menu_items(menu_items)
        if menu_items.present?
          content_tag(list_tag, :class => menu_items_css(menu_items)) do
            menu_items.each_with_index.inject(ActiveSupport::SafeBuffer.new) do |buffer, (item, index)|
              buffer << render_menu_item(item, index)
            end
          end
        end
      end


      def check_for_dropdown_item(menu_item)
        ( menu_item != roots.first ) && ( menu_item_children( menu_item ).count > 0 )
      end

      def menu_items_css(menu_items)
        css = []

        css << list_first_css if (roots == menu_items)
        css << list_dropdown_css if (roots != menu_items)

        css.reject(&:blank?).presence

      end


      def menu_item_css(menu_item, index)
        css = []

        css << list_item_dropdown_css if (check_for_dropdown_item(menu_item))
        css << selected_css if selected_item_or_descendant_item_selected?(menu_item)
        css << first_css if index == 0
        css << last_css if index == menu_item.shown_siblings.length

        css.reject(&:blank?).presence
      end

      def render_menu_item(menu_item, index)

          if check_for_dropdown_item(menu_item)
              menu_item_class = list_item_dropdown_css
          else
              menu_item_class =  menu_item_css(menu_item, index)
          end

          content_tag(list_item_tag, :class => menu_item_class) do
              @cont = context.refinery.url_for(menu_item.url)
              buffer = ActiveSupport::SafeBuffer.new
              buffer << link_to(menu_item.title, context.refinery.url_for(menu_item.url))
              buffer << render_menu_items(menu_item_children(menu_item))
              buffer
          end
      end


    end
  end
end

I have a helper in app/helpers/application_helpers.rb:

module ApplicationHelper
    def zurb_menu
        menu_items = Refinery::Menu.new(Refinery::Page.menu_pages)
        presenter = Refinery::Pages::ZurbMenuPresenter.new(menu_items, self)
        presenter
    end
...

Then just call zurb_menu from the _header. I'm doing the Navbar stuff explicitly in my header function, which may or may not be right; you could roll that into the ZurbMenuPresenter class, and I may well do so:

app/views/refinery/_header.html.erb

<nav class="top-bar hide-for-small">
<ul class="title-area">

    <li class="name">
    <h1><a href="/">Home</a></h1>
    </li>
    <li class="toggle-topbar menu-icon"><a href="#"><span>Menu</span></a></li>
</ul>
<script src="http://foundation.zurb.com/public/assets/marketing_docs.js"></script>
<%=
    zurb_menu.to_html
%>

</nav>

You'll need to override the MenuPresenter. Specifically, you'll need to add the appropriate classes to the children of the top-level menu with the render_menu_item function. I'm not too familiar with Zerb Foundation, but this should get you started.

Note: untested code, I just switched in some class names from my own Bootstrap menu solution to get you started, you might have to do a bit more work. I'm also adding your helper code to the overridden presenter, so you can just call it in a view like this: <%= Refinery::ZerbMenuPresenter.new(refinery_menu_pages, self).to_html %>

app/presenters/refinery/zerb_menu_presenter.rb

module Refinery
  class ZerbMenuPresenter < ::Refinery::MenuPresenter
    self.css = "top-bar-section"
    self.dom_id = nil
    self.menu_tag = :section
    self.list_tag = "ul class='left'"
    def render_menu_item(menu_item, index)
      content_tag(list_item_tag, :class => menu_item_css(menu_item, index)) do
        buffer = ActiveSupport::SafeBuffer.new
        if menu_item_children(menu_item).present?
          buffer << link_to("#{menu_item.title}", context.refinery.url_for(menu_item.url), :class => 'has-dropdown')
          buffer << render_menu_items(menu_item_children(menu_item), 'dropdown')
        else
          buffer << link_to(menu_item.title, context.refinery.url_for(menu_item.url))
        end
        buffer
      end
    end
  end
end
