使用awesome嵌套集的动态树菜单

Question

如何在rails中使用awesome嵌套集（或任何其他set插件）创建动态树菜单助手？结果看起来应该是这样的：

<div class="level_0">
  <span class="title">Categroy</span>
  <div class="level_1>
    <span class="title">SubCategroy</span>

    <div class="level_2>
      SubSubcategory
      SubSubcategory
      SubSubcategory
      SubSubcategory
      SubSubcategory
    </div>

    <span class="title">SubCategroy</span>

    <div class="level_2>
      SubSubcategory
      SubSubcategory
      SubSubcategory
      SubSubcategory
      SubSubcategory
    </div>

  </div>

  <div class="level_1>
    <span class="title">SubCategroy</span>

    <div class="level_2>
      SubSubcategory
      SubSubcategory
      SubSubcategory
      SubSubcategory
      SubSubcategory
    </div>

    <span class="title">SubCategroy</span>

    <div class="level_2>
      SubSubcategory
      SubSubcategory
      SubSubcategory
      SubSubcategory
      SubSubcategory
    </div>

  </div>
</div>
