dsucuz如何调用主导航

discuz默认的主导航样式不好自定义，再有当主导航固定时下拉的菜单不跟随滚动。

下面的代码可以自己查询调用，样式和特效自由度高一些。

<ul id="menu-navigation" class="menu">

<!--{eval $navs = DB::fetch_all("SELECT * FROM ".DB::table('common_nav')." WHERE `available` > 0 and `navtype` = 0 and `parentid` = 0 ORDER BY `displayorder` ASC");}-->

<!--{loop $navs $nav}-->

<!--{eval $subnavs = DB::fetch_all("SELECT * FROM ".DB::table('common_nav')." WHERE `available` > 0 and `navtype` = 0 and `parentid` = $nav[id] ORDER BY `displayorder` ASC");}-->

<!--{eval $subs = DB::result(DB::query("SELECT name FROM ".DB::table('common_nav')." WHERE available > '0' and navtype = '0' and parentid = '$nav[id]'"));}-->

<li<!--{if $subs}--> class="current-menu-parent menu-item-has-children"<!--{/if}--> >

        <a href="$nav[url]"{if $nav[target] == 1}  target="_blank"{/if} style="">

                <!--{if $nav[logo]}-->

                <img src="data/attachment/common/$nav[logo]" style=" max-width: 25px; margin: -3px -3px 0 0;"/>

                <!--{/if}-->$nav[name]</a>        

                <!--{if $subs}-->                                

                <ul class="sub-menu">

                        <!--{loop $subnavs $subnav}-->

      <li>

        <a href="$subnav[url]"{if $subnav[target] == 1}  target="_blank"{/if} style="">

         $subnav[name]

        </a>

      </li>

      <!--{/loop}-->

    </ul>

    <!--{ad/subnavbanner/a_mu}-->        

    <!--{/if}-->                        

</li>

<!--{/loop}-->

</ul>

样式和js就不带了，网上特效很多往里套就行。
