网络上有类似的文章，但是都是不全，错误的方法。以下是本站长整理出来亲身验证无误的方法.
1.在\dede\templets\diy_list.htm 找到（大约在41行）：   
else if($fielddata[1]=='addon')
{
    $fields[$field] = "<a href='{$fields[$field]}' target='_blank'><img src='images/channeladd.gif' border='0' /> 其它附件</a>";
}
在下面加入：   
//联动类型显示修正开始
 
            else if($fielddata[1]=='stepselect')
            {
                $db->Execute('me',"SELECT * FROM `dede_stepselect` WHERE egroup='{$field}'");
                while($arr = $db->GetArray(me))
                {
                    $egroup = $arr['egroup'];
                }
                $fields[$field] = Getenums("{$fields[$field]}",$egroup);
            }
 
//联动类型显示修正结束www.80zhan.com织梦模板下载
继续找到：   
{/dede:datalist}
在下面加入：   
<?php
function Getenums($evalue = 0, $egroup)
{
    if (!isset($GLOBALS['em_' . $egroup . 's'])) {
        $cachefile = DEDEDATA . '/enums/' . $egroup . '.php';
        if (!file_exists($cachefile)) {
            require_once DEDEINC . '/enums.func.php';
            WriteEnumsCache();
        }
        if (!file_exists($cachefile)) {
            return '';
        } else {
            require_once $cachefile;
        }
    }
    if ($evalue >= 500) {
        if ($evalue % 500 == 0) {
            return isset($GLOBALS['em_' . $egroup . 's'][$evalue]) ? $GLOBALS['em_' . $egroup . 's'][$evalue] : '';
        } else {
            if (preg_match('#([0-9]{1,})\\.([0-9]{1,})#', $evalue, $matchs)) {
 
$esonvalue = $matchs[1];
$etopvalue = $esonvalue - $esonvalue % 500;
$esecvalue = preg_replace('/(?<=\.)[0]+/', '', $evalue);
 
$GLOBALS['em_' . $egroup . 's'][$etopvalue] = empty($GLOBALS['em_' . $egroup . 's'][$etopvalue]) ? '' : $GLOBALS['em_' . $egroup . 's'][$etopvalue];
 
$GLOBALS['em_' . $egroup . 's'][$esonvalue] = empty($GLOBALS['em_' . $egroup . 's'][$esonvalue]) ? '' : $GLOBALS['em_' . $egroup . 's'][$esonvalue];
 
$GLOBALS['em_' . $egroup . 's'][$esecvalue] = empty($GLOBALS['em_' . $egroup . 's'][$esecvalue]) ? '' : $GLOBALS['em_' . $egroup . 's'][$esecvalue];
 
return $GLOBALS['em_' . $egroup . 's'][$etopvalue] . ' - ' . $GLOBALS['em_' . $egroup . 's'][$esonvalue] . ' - ' . $GLOBALS['em_' . $egroup . 's'][$esecvalue];
            }
                            else
                            {
$elimit = $evalue % 500;
$erevalue = $evalue - $elimit;
$GLOBALS['em_' . $egroup . 's'][$erevalue] = empty($GLOBALS['em_' . $egroup . 's'][$erevalue]) ? '' : $GLOBALS['em_' . $egroup . 's'][$erevalue];
$GLOBALS['em_' . $egroup . 's'][$evalue] = empty($GLOBALS['em_' . $egroup . 's'][$evalue]) ? '' : $GLOBALS['em_' . $egroup . 's'][$evalue];
return $GLOBALS['em_' . $egroup . 's'][$erevalue] . ' - ' . $GLOBALS['em_' . $egroup . 's'][$evalue];
            }
        }
    }
}
?>

修改完毕。
需要注意的是：添加新字段时候，表单提示文字必须和联动的组类别名一致，比如我要添加一个表单提示文字是“课程”，那么新增联动类别组的时候类别名也要填写“课程”
