    一、修改文件:\include\taglib目录下的channel.lib.php

    <?php
    function lib_channel(&$ctag,&$refObj)
    {
    global $_sys_globals,$envs,$dsql;
    $attlist = "typeid|0,reid|0,row|100,col|1,type|son,currentstyle|";
    FillAttsDefault($ctag->CAttribute->Items,$attlist);
    extract($ctag->CAttribute->Items, EXTR_SKIP);
    $innertext = $ctag->GetInnerText();
    $cacheid = trim($cacheid);
    if($cacheid !='') {
    $likeType = GetCacheBlock($cacheid);
    if($likeType != '') return $likeType;
    }

    $reid = 0;
    $topid = 0;
    if(empty($typeid) && $envs['typeid']!=0)
    {
    $typeid = $envs['typeid'];
    $reid = $envs['reid'];
    }else{
    $reid=0;
    }
    if($type==''||$type=='sun') $type="son";
    if($innertext=='') $innertext = GetSysTemplets("channel_list.htm");
    if($reid==0 && $typeid>0)
    {
    $dbrow = $dsql->GetOne("Select reid From dede_arctype where id='$typeid' ");
    if(is_array($dbrow)) $reid = $dbrow['reid'];
    }
    $likeType = '';
    if($type=='top')
    {
    $sql = "Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath,description
    From dede_arctype where reid=0 And ishidden<>1 order by sortrank asc limit 0,$row";
    }
    else if($type=="son")
    {
    //if($_sys_globals['typeid']>0) $typeid = $_sys_globals['typeid'];
    if($typeid==0) {
    return '';
    }
    $sql = "Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath,description
    From dede_arctype where reid='$typeid' And ishidden<>1 order by sortrank asc limit 0,$row";
    }
    else if($type=="self")
    {
    if($reid==0) {
    return '';
    }
    $sql = "Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath,description
    From `dede_arctype` where reid='$reid' And ishidden<>1 order by sortrank asc limit 0,$row";
    }
    //And id<>'$typeid'
    $needRel = false;
    $dtp2 = new DedeTagParse();
    $dtp2->SetNameSpace("field","[","]");
    $dtp2->LoadSource($innertext);
    $dsql2 = clone $dsql;
    $dsql->SetQuery($sql);
    $dsql->Execute();
    $line = $row;
    //检查是否有子栏目,并返回rel提示(用于二级菜单)
    if(ereg(':rel', $innertext)) $needRel = true;

    if(empty($sql)) return '';
    $dsql->SetQuery($sql);
    $dsql->Execute();

    $totalRow = $dsql->GetTotalRow();
    $GLOBALS['autoindex'] = 0;
    for($i=0;$i < $line;$i++)

    if($needRel)
    {
    $row['sonids'] = GetSonIds($row['id'], 0, false);
    if($row['sonids']=='') $row['rel'] = '';
    else $row['rel'] = " rel='dropmenu{$row['id']}'";
    }
    //处理同级栏目中,当前栏目的样式
    if( ($row['id']==$typeid || ($topid==$row['id'] && $type=='top') ) && $currentstyle!='' )
    {
    if($currentstyle!='')
    {
    $linkOkstr = $currentstyle;
    $row['typelink'] = GetOneTypeUrlA($row);
    $linkOkstr = str_replace("~rel~",$row['rel'],$linkOkstr);

    }
    }else
    {
    $row['typelink'] = $row['typeurl'] = GetOneTypeUrlA($row);
    if(is_array($dtp2->CTags))
    {
    foreach($dtp2->CTags as $tagid=>$ctag){
    if(isset($row[$ctag->GetName()]))
    {
    $dtp2->Assign($tagid,$row[$ctag->GetName()]);
    }
    elseif (preg_match('/^sonchannel[0-9]*$/',$ctag->GetName()))
    {
    $dtp2->Assign($tagid,lib_channel_son($ctag,$row['id'],$dsql2));
    }
    }
    }
    $likeType .= $dtp2->GetResult();
    }
    }
    if($col>1) $likeType .= "</dd>\r\n";
    $GLOBALS['autoindex']++;
    }//Loop Col
    if($col>1)
    {
    $i += $col - 1;
    $likeType .= " </dl>\r\n";
    }
    }//Loop for $i
    reset($dsql2);
    $dsql->FreeResult();
    return $likeType;
    }
    function lib_channel_son($ctag,$typeid = 0,$dsql2)
    {
    $attlist = "row|100,col|1,currentstyle|";
    FillAttsDefault($ctag->CAttribute->Items,$attlist);
    extract($ctag->CAttribute->Items, EXTR_SKIP);
    $innertext = $ctag->GetInnerText();
    $dsql3 = clone $dsql2;
    $likeType = '';
    //if($_sys_globals['typeid']>0) $typeid = $_sys_globals['typeid'];
    if($typeid==0) {
    return '';
    }
    $sql = "Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath,description
    From dede_arctype where reid='$typeid' And ishidden<>1 order by sortrank asc limit 0,$row";
    //And id<>'$typeid'

    if(is_array($dtp2->CTags))
    {
    foreach($dtp2->CTags as $tagid=>$ctag){
    if(isset($row[$ctag->GetName()]))
    {
    $dtp2->Assign($tagid,$row[$ctag->GetName()]);
    }
    elseif (preg_match('/^sonchannel[0-9]*$/',$ctag->GetName()))
    {
    $dtp2->Assign($tagid,lib_channel_son($ctag,$row['id'],$dsql3));
    }
    }
    }
    $likeType .= $dtp2->GetResult();
    }
    if($col>1) $likeType .= "</dd>\r\n";
    }//Loop Col
    if($col>1)
    {
    $i += $col - 1;
    $likeType .= " </dl>\r\n";
    }
    }//Loop for $i
    reset($dsql3);
    $dsql2->FreeResult();
    return $likeType;
    }
    ?>

    复制这个文件覆盖旧文件。

    二:巧用sonchannel标签做三级菜单

    {dede:channelartlist typeid='72'}

    {/dede:channelartlist}    //调用顶级栏目(一级菜单)

    dede:channel type='son'}

    {/dede:channel} //二级菜单

    [field:sonchannel0]//无限获取三级菜单

    实例:

    div class="nav">
    <div class="nav-l">
    <a href="/"><span class="nav-l-span">顶级菜单<i></i></span> </a>
    <div class="nav-submenu">
    <div id="submenu">
    {dede:channelartlist typeid='72'}
    <div class="submenu1">
    <h3 class="submenu1-t1"><a href="{dede:field name='typeurl'/}">{dede:field name='typename'/}</a></h3>
    </div>
    {/dede:channelartlist}
    </div>
    </div>

    <div class="nav-submenu-xl">

    {dede:channelartlist typeid='72'}

    <div class="xl-menu" style="top:1px;display:none;">

    <div class="xl-menu-l xl-menu-wc">
    <div class="xl-menu-l-part">

    {dede:channel type='son'}

    <div id="xl-menu-l-div3">
    <div class="xl-menu-l-div3-b">

    <b> <a href="[field:typelink/]">[field:typename/]</a></b>

    </div>
    <div class="xl-menu-l-div3-p">

    <p>[field:sonchannel0] <a href="[field:typelink/]">[field:typename/]</a> |[/field:sonchannel0] </p>
    </div>

    </div>
    {/dede:channel}
    </div>
    </div>
    </div>
    {/dede:channelartlist}
    </div>
    </div>

    注:这里顶级菜单我调用了两次,大家按照自己的需求来!
