                              :custom_options_attributes => [ { :name => "male" }, { :name => "female" } ] 
                             }

  @from.build_form_field {type: :radio, :title: "性別", 
                            :custom_options_attributes => [ { :name => "male" }, { :name => "female" } ] 
                          }

    <% @user.form_fields.each do | field |%>
        <%=render_input @user, field%>
    <% end %>
    <%=f.submit%>
<% end %>
