Rails simple navigation, nested set

Question

I built navigation menu using simple navigation and built nested categories which i display in this menu.

navigation.rb code:

  navigation.items do |primary|
    Category.roots.map do |root|
      primary.item ":root_#{root.id}", root.title, category_path(root) do |secondary|
        root.descendants.map do |desc|
          secondary.item ":desc_#{desc.id}", desc.title, category_path(desc)
        end
      end
    end
  end

The question is: how can i display all the levels of categories in my menu. That code does only with two level nesting.

Thank in advance

You will have to use recursive if this helps at all, you can see an example here: Recursive Rails Nested Resources
