群组推荐到论坛板块后无法横排显示，后台没有这个设置功能，默认一排只能显示一个群组，与上面横排显示的论坛板块不是很协调，如下图：

怎样才能横排显示推荐的群组呢，如下图：
 

这里讲一个方法，两步可以实现，需要修改程序和模板：
一、找到程序文件的"\source\module\forum\forum_forumdisplay.php"的305-312行：

if($_G['forum']['modrecommend'] && $_G['forum']['modrecommend']['open']) {  
        $_G['forum']['recommendlist'] = recommendupdate($_G['fid'], $_G['forum']['modrecommend'], '', 1);  
}  
$recommendgroups = array();  
if($_G['forum']['status'] != 3 && $_G['setting']['groupstatus']) {  
        loadcache('forumrecommend');  
        $recommendgroups = $_G['cache']['forumrecommend'][$_G['fid']];  
} 

修改为：

if($_G['forum']['modrecommend'] && $_G['forum']['modrecommend']['open']) {  
        $_G['forum']['recommendlist'] = recommendupdate($_G['fid'], $_G['forum']['modrecommend'], '', 1);  
}  
$recommendgroups = array();  
if($_G['forum']['status'] != 3 && $_G['setting']['groupstatus']) {  
        loadcache('forumrecommend');  
        $recommendgroups = $_G['cache']['forumrecommend'][$_G['fid']];  
}  
 
$_G['groups']['forumcolumns'] = 3 ;  
$_G['groups']['forumcolwidth'] = (floor(100 / $_G['groups']['forumcolumns']) - 0.1).'%';  
$_G['groups']['endrows'] = '';  
if($colspan = count($recommendgroups) % $_G['groups']['forumcolumns']) {  
        while(($_G['groups']['forumcolumns'] - $colspan) > 0) {  
                $_G['groups']['endrows'] .= '<td> </td>';  
                $colspan ++;  
        }  
        $_G['groups']['endrows'] .= '</tr>';  
} 

“$_G['groups']['forumcolumns'] = 3 ;”的值，既是横排显示的个数，可自由修改。

二、找到模板文件"\template\default\forum\forumdisplay.htm"的126-150行

<table cellspacing="0" cellpadding="0" class="fl_tb"> 
                                                        <!--{loop $recommendgroups $key $group}--> 
                                                        <tr {if $key != 0}class="fl_row"{/if}> 
                                                                <td class="fl_icn"> 
                                                                        <a href="forum.php?mod=group&fid=$group[fid]"

                                                                </td> 
                                                                <td> 
                                                                        <h2><a href="forum.php?mod=group&fid=$group[fid]" 
target="_blank">$group[name]</a><span class="xg1 xw0"> ($group[membernum] {lang activity_member_unit})</span></h2> 
                                                                        <p><!--{echo cutstr($group[description], 100)}--></p> 
                                                                </td> 
                                                                <td class="fl_i"> 
                                                                        <span class="xi2">$group[threads] {lang index_threads}</span>

                                                                <td class="fl_by"> 
                                                                        <div> 
                                                                                <!--{if is_array($group['lastpost'])}--> 
                                                                                <a href="forum.php?mod=redirect&tid=$group

                                                                                <!--{else}--> 
                                                                                {lang never}  
                                                                                <!--{/if}--> 
                                                                        </div> 
                                                                </td> 
                                                        </tr> 
                                                        <!--{/loop}--> 
                                                </table>
