帝国cms首页导航条如何调用一级、二级栏目？

                        <div class="collapse navbar-collapse" id="example-navbar-collapse">
                            <ul id="menu-%e5%af%bc%e8%88%aa%e8%8f%9c%e5%8d%95" class="nav navbar-nav">
<li class="menu-item menu-item-type-custom menu-item-object-custom current-menu-item current_page_item menu-item-home menu-item-11 active"><a title="网站首页" href="/">网站首页</a></li>
[e:loop={"select classid,classname,classpath,classimg from [!db.pre!]enewsclass where bclassid='0' and showclass=0 order by myorder asc,classid asc",0,24,0}]

<?
$cr=$empire->fetch1("select classid from {$dbtbpre}enewsclass where bclassid = '".$bqr[classid]."' limit 1"); 
if ($cr[classid]){
?>
<!--判断是否有子栏目，如果有出现子栏目样式，如果没有出现一级栏目的样式-->
<li class="menu-item menu-item-type-post_type menu-item-object-page menu-item-has-children dropdown">
<a title="<?=$bqr[classname]?>" href="<?=$public_r[newsurl].$bqr[classpath]?>/" data-toggle="dropdown" class="dropdown-toggle" aria-haspopup="true"><?=$bqr[classname]?>
