菜单-系统定义效果

菜单效果效果一：链接简略化
```html
<ul class="nav navbar-nav navbar-right">
 <li class="Lev1 drop" id="nav_0">
 <a href="/" class="menu1 {if condition="$topcid eq 'index'" } active{/if}">
 首页
 </a>
 </li>
 {volist name="cateRes" id="cate" key="k"}
 <li class="Lev1 drop" id="nav_{$k}">
 <a href="{$cate.cate_attr|makeurl=###,$cate.id}" class="menu1 {if condition="$cate.id eq $cid"}active{/if}">
 {$cate.cate_name}
 {if condition="$cate.children" }
 
 
 {/if}
 </a>
 {if condition="$cate.children" }
 <ul class="drop-down sub-menu2">
 {volist name="$cate['children']" id="sonCate"}
 <li class="Lev2">
 <a href="{$sonCate.cate_attr|makeurl=###,$sonCate.id}" class="menu2">
 {$sonCate.cate_name}
 </a>
 </li>
 {/volist}
 </ul>
 {/if}
 </li>
 {/volist}

</ul>
```
菜单效果效果二：链接完整，制作复杂些，但是显示效果更加好
```html
 <ul class="nav navbar-nav">
 <li {if condition="$topcid eq 'index'" } class="current" {/if}><a href="/">网站首页</a></li>
 {volist name="cateRes" id="cate"}
 <li class="dropdown">
 <a href="{if condition="$cate['cate_attr'] eq 1"}{:url('index/cate/index',array('cid'=>$cate['id']))}{/if}
 {if condition="$cate['cate_attr'] eq 2"}{:url('index/page/index',array('cid'=>$cate['id']))}{/if}
 {if condition="$cate['cate_attr'] eq 3"}{$cate.link}{/if}">{$cate.cate_name}</a>
 <ul class="dropdown-menu nav_small" role="menu">
 {volist name="$cate['children']" id="sonCate"}
 <li>
 <a href="{if condition="$sonCate['cate_attr'] eq 1"}{:url('index/cate/index',array('cid'=>$sonCate['id']))}{/if}
 {if condition="$sonCate['cate_attr'] eq 2"}{:url('index/Page/index',array('cid'=>$sonCate['id']))}{/if}
 {if condition="$sonCate['cate_attr'] eq 3"}{$sonCate.link}{/if}
 " target="">{$sonCate.cate_name}</a>
 
 </li>
 {/volist}
 </ul>
 </li>
 {/volist}

</ul>
```

判断 是否是首页` {if condition="$topcid eq 'index'" } active{/if}`
循环输出一级菜单`{volist name="cateRes" id="cate" key="k"}  {/volist}`
一级菜单链接 `{$cate.cate_attr|makeurl=###,$cate.id}`
一级菜单栏目名称 `{$cate.cate_name}`
判断是否有二级菜单 ` {if condition="$cate.children" }{/if}`
二级菜单循环`  {volist name="$cate['children']" id="sonCate"}{/volist}`
二级菜单链接 `{$sonCate.cate_attr|makeurl=###,$sonCate.id}`
二级菜单栏目名称 `{$sonCate.cate_name}`
