Rails Bootstrap Navbar and refineryCMS

Question

Does anyone have implemented the Rails Bootstrap Navbar in refineryCMS?

I'm having a hard time trying to figure out how to render the dropdown menu.

which should be the right way of accomplish this?

_menu.html.erb

<%    
  if (roots = local_assigns[:roots] || (collection ||= refinery_menu_pages).roots).present?
    dom_id ||= 'menu'
  css = [(css || 'menu'), 'clearfix'].flatten.join(' ')
    hide_children = Refinery::Core.menu_hide_children if hide_children.nil?
-%>
<div class="navbar">
  <div class="navbar-inner">
    <div class="container">

      <nav id='<%= dom_id %>' class='<%= css %> nav'>
        <ul class="nav">


          <%= render :partial => '/refinery/menu_branch', :collection => roots,
                     :locals => {
                       :hide_children => hide_children,
                       :sibling_count => (roots.length - 1),
                       :menu_levels => local_assigns[:menu_levels],
                       :apply_css => true #if you don't care about class='first' class='last' or class='selected' set apply_css to false for speed.
                     } -%>

        </ul>
        </nav>
    </div>
    </div>
</div>
<% end -%>

_menu_branch.html.erb

<%
  if !!local_assigns[:apply_css] and (classes = custom_menu_branch_css(local_assigns)).any?
    css = "class='#{classes.join(' ')}'".html_safe
  end

-%>
<li class="dropdown">
<% if menu_branch.children.present? &&  menu_branch.ancestors.length < 1 %>
<%= link_to(menu_branch.title, refinery.url_for(menu_branch.url), class: "dropdown-togle", data: { toggle: "dropdown" }) -%>
<% else %>
<%= link_to(menu_branch.title, refinery.url_for(menu_branch.url)) -%>
<% end %>
  <% if ( (children = menu_branch.children unless hide_children).present? &&
          (!local_assigns[:menu_levels] || menu_branch.ancestors.length < local_assigns[:menu_levels]) ) -%>


      <ul class="dropdown-menu">
      <%= render :partial => '/refinery/menu_branch', :collection => children,
                 :locals => {
                   :apply_css => local_assigns[:apply_css],
                   :hide_children => !!hide_children,
                   :menu_levels => local_assigns[:menu_levels]
                  } -%>

    </ul>
</li>
<% end -%>

nav_bar snippet

<%= nav_bar :fixed => :top, :brand => "Fashionable Clicheizr 2.0", :responsive => true do %>
    <%= menu_group do %>
        <%= menu_item "Home", root_path %>
        <%= menu_divider %>

Faced for some hours with same issue. Have solution with bit more pretty code (or just more close to refinery standarts), I believe, its better to override base Refinery menu_presenter first of all take a look a bit simmilar quest http://refinerycms.com/guides/menu-presenter and this one too: http://refinerycms.com/guides/extending-controllers-with-decorators

So. Based on that article lets do this

app/decorators/models/refinery/page_decorator.rb:

Refinery::Page.class_eval do
  def self.menu_pages
    where :show_in_menu => true
  end
end

app/helpers/application_helper.rb

module ApplicationHelper
  def menu_header
    menu_items = Refinery::Menu.new(Refinery::Page.menu_pages)

    presenter = Refinery::Pages::MenuPresenter.new(menu_items, self)
    presenter.first_css = nil
    presenter.last_css = nil

    presenter
  end
end

in terminal run:

cd /path/to/app/
rake refinery:override presenter=refinery/pages/menu_presenter

It will generate app/presenters/refinery/pages/menu_presenter.rb change it to this:

require 'active_support/core_ext/string'
require 'active_support/configurable'
require 'action_view/helpers/tag_helper'
require 'action_view/helpers/url_helper'

module Refinery
  module Pages
    class MenuPresenter
      include ActionView::Helpers::TagHelper
      include ActionView::Helpers::UrlHelper
      include ActiveSupport::Configurable

      config_accessor :roots, :menu_tag, :list_tag, :list_item_tag, :css, :dom_id,
                      :max_depth, :selected_css, :first_css, :last_css, :list_first_css,
                      :list_dropdown_css, :list_item_dropdown_css,
                      :list_item__css, :link_dropdown_options, :carret

      self.dom_id = :div
      self.css = ["nav-collapse", "collapse", "navbar-responsive-collapse"]
      self.menu_tag = :nav
      self.list_tag = :ul
      self.list_first_css = :nav
      self.carret = '<b class="caret"></b>'
      self.list_dropdown_css = "dropdown-menu"
      self.link_dropdown_options = {class: "toggle-dropdown", data: {:toggle=>"dropdown"}}
      self.list_item_tag = :li
      self.list_item_dropdown_css = :dropdown
      self.list_item__css = nil
      self.selected_css = :active
      self.first_css = :first
      self.last_css = :last
      def roots
        config.roots.presence || collection.roots
      end

      attr_accessor :context, :collection
      delegate :output_buffer, :output_buffer=, :to => :context

      def initialize(collection, context)
        @collection = collection
        @context = context
      end

      def to_html
        render_menu(roots) if roots.present?
      end

      private
      def render_menu(items)
        content_tag(menu_tag, :id => dom_id, :class => css) do
          render_menu_items(items)
        end
      end

      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 render_menu_item(menu_item, index)
        content_tag(list_item_tag, :class => menu_item_css(menu_item, index)) do
          @cont = context.refinery.url_for(menu_item.url)
          buffer = ActiveSupport::SafeBuffer.new
            if check_for_dropdown_item(menu_item)
              buffer << link_to((menu_item.title+carret).html_safe, "#", link_dropdown_options)
            else
              buffer << link_to(menu_item.title, context.refinery.url_for(menu_item.url))
            end
          buffer << render_menu_items(menu_item_children(menu_item))
          buffer
        end
      end

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

      # Determines whether any item underneath the supplied item is the current item according to rails.
      # Just calls selected_item? for each descendant of the supplied item
      # unless it first quickly determines that there are no descendants.
      def descendant_item_selected?(item)
        item.has_children? && item.descendants.any?(&method(:selected_item?))
      end

      def selected_item_or_descendant_item_selected?(item)
        selected_item?(item) || descendant_item_selected?(item)
      end

      # Determine whether the supplied item is the currently open item according to Refinery.
      def selected_item?(item)
        path = context.request.path
        path = path.force_encoding('utf-8') if path.respond_to?(:force_encoding)

        # Ensure we match the path without the locale, if present.
        if %r{^/#{::I18n.locale}/} === path
          path = path.split(%r{^/#{::I18n.locale}}).last.presence || "/"
        end

        # First try to match against a "menu match" value, if available.
        return true if item.try(:menu_match).present? && path =~ Regexp.new(item.menu_match)

        # Find the first url that is a string.
        url = [item.url]
        url << ['', item.url[:path]].compact.flatten.join('/') if item.url.respond_to?(:keys)
        url = url.last.match(%r{^/#{::I18n.locale.to_s}(/.*)}) ? $1 : url.detect{|u| u.is_a?(String)}

        # Now use all possible vectors to try to find a valid match
        [path, URI.decode(path)].include?(url) || path == "/#{item.original_id}"
      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 menu_item_children(menu_item)
        within_max_depth?(menu_item) ? menu_item.children : []
      end

      def within_max_depth?(menu_item)
        !max_depth || menu_item.depth < max_depth
      end

    end
  end
end

almost done. add menu_header.to_html to your menu inside container of your menu like this:

    <div class="navbar navbar-fixed-top">
      <div class="navbar-inner">
        <div class="container">
          <a class="btn btn-navbar" data-toggle="collapse" data-target=".nav-collapse">
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
          </a>
          <a class="brand" href="#"><%=Refinery::Core::site_name %></a>
          <%= menu_header.to_html %>
        </div>
      </div>
    </div>
