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}
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}
第三级替换为二级正文
{pboot:nav} <a href="[nav:link]">[nav:name]</a> {pboot:2nav parent=[nav:scode]} <a href="[2nav:link]">[2nav:name]</a> {pboot:list scode=[2nav:scode] num=10} <li><a href="[list:link]">[list:title]</a></li> {/pboot:list} {/pboot:2nav} {/pboot:nav}
