Answer 1

Thanks everyone, I did it like this:

class ApplicationController < ActionController::Base
  helper_method :menu
  def menu
  	Menu.all
  end
end

<% menu.each do |item| %>
<li>
  <a href="<%= item.link %>"><%= item.name %></a>
</li>
<% end %>

In your case something like this:

# В конфиурационном файле:
SimpleNavigation::Configuration.run do |navigation|  
  navigation.items do |menu|
    Menu.all.each do |m|
      menu.item m.name.to_sym, m.name, menu_path(m)
    end
  end
end

# В layout'e:
<%= render_navigation %>
