我如何用div标签包围来自表单的多个输入？

<%= simple_form_for(@evaluation) do |f| %>
  <%= f.error_notification %>

  <div class=\"toggle\">

    <div class=\"toggle_selector\">
      <%= f.input :was_answered, :as => :radio, :collection => [:yes, :no, \'?\'] %>
    </div>

    <div class=\"toggle_content\">
      <%= f.input :name %>
      <%= f.input :answer %>
      <%= f.input :score %>
    </div>

  </div>

  <div class=\"actions\">
    <%= f.button :submit %>
  </div>
<% end %>

def toggling_field_for form, selector, &block                            
  content_tag :div, :class => \'toggle\' do                                
    %{#{toggle_selector form, selector}                                  
      #{toggle_content &block if block_given?}                           
    }.html_safe                                                          
  end
