want a suckerfish dropdown?

  def suckerfish(node)
    fuc = lambda do |nodes|
      return "" if nodes.empty?
      return "<ul>" +
        nodes.inject("") do |string, (node, children)|
          string + "<li rel='#{node.id}'>" +
          link_to(node.name, node.path) +
          fuc.call(children) +
          "</li>"
        end +
        "</ul>"
    end
    fuc.call(node.descendants.arrange)
  end

For Rails 3 & 4, if you want to use this method in views as a helper_method :suckerfish add view_context before link_to:

  view_context.link_to(node.name, node.path) +  # don't forget to set your path
