Refinery CMS を最新バージョン (2.1.0) にアップグレードしました。ナビゲーション メニューのレンダリングに新しいアプローチがあります。

(部分的に_header.html.erb)

<%= Refinery::Pages::MenuPresenter.new(refinery_menu_pages, self).to_html %>

同じパーシャルの古いバージョン:

<%= render(:partial => "/refinery/menu", :locals => {
         :dom_id => 'menu',
         :css => 'menu'
       }) %>

を使用してナビゲーションバーにブートストラップ スタイルを追加するにはどうすればよいMenuPresenterですか?
