1、导航菜单列表

{pboot:nav}
<a href="[nav:link]">[nav:name]</a>
{/pboot:nav}

2、二级嵌套

{pboot:nav}
  <a href= "[nav:link]">[nav:name]</a>
  {pboot:2nav parent=[nav:scode]}
    <a href= "[2nav:link]">[2nav:name]</a>
  {/pboot:2nav}
{/pboot:nav}

3、三级嵌套

{pboot:nav}                   
  <a href= "[nav:link]">[nav:name]</a>
  {pboot:2nav parent=[nav:scode]}
    <a href= "[2nav:link]">[2nav:name]</a>
    {pboot:3nav parent=[2nav:scode]}
      <a href= "[3nav:link]">[3nav:name]</a>
    {/pboot:3nav}
  {/pboot:2nav}
{/pboot:nav}
