  [@cms_content_list count='6' orderBy='7' titLen='19' channelId='14,40'  channelOption='1']
                    [#list tag_list as a]
                    <li>
                    <a href="${a.url}" title="${a.title}" target="_blank">[@text_cut s=a.title len=titLen /]</a>
                    [@text_cut s=a.txt!  len=titLen /]
