极致cms输出多层级导航高亮，代码如下：
- {foreach $classtypedata as $v}
- {if($v['pid']==0 && $v['isshow']==1)}
- //输出一级
- <li>{$v['classname']}</li>
- {foreach $v['children']['list'] as $vv}
- {if($vv['isshow']==1)}
- //输出二级
- <li {if(isset($type) && in_array($type['id'],$vv['children']['ids']))}class="cur"{/if}>{$vv['classname']}</li>
- {foreach $vv['children']['list'] as $vvv}
- {if($vvv['isshow']==1)}
- //输出三级
- <li {if(isset($type) && in_array($type['id'],$vvv['children']['ids']))}class="cur"{/if}>{$vvv['classname']}</li>
- {/if}
- {/foreach}
- {/if}
