无规律推荐位标签的嵌套使用

这种布局的页面，要做推荐位的话，往往需要做3个推荐位。但这样就得维护3个推荐位内容。

其实可以通过简单粗暴的方式 一个推荐位即可搞定。

如下代码：

 {wz:content action="block" pagesize="6" type="1" blockid="18"}
<div class="col-xs-6">
                    <div class="narrowArt">
                        <a href="{$rs[0]['url']}" title="222">
                            <img  src="{$rs[0]['thumb']}" height="380">
                            <h1>{$rs[0]['title']}</h1>
                        </a>
                    </div>
                </div>
                <div class="col-xs-3">
                    <div class="narrowArt poto">
                        <a href="{$rs[1]['url']}" title="222">
                            <img  src="{imagecut($rs[1]['thumb'],273,182)}" height="">
                            <h2>{$rs[1]['title']}</h2>
                        </a>
                    </div>
                    <div class="narrowArt poto">
                        <a href="{$rs[2]['url']}" title="222">
                            <img  src="{imagecut($rs[2]['thumb'],273,182)}" alt="" height="">
                            <h2>{$rs[2]['title']}</h2>
                        </a>
                    </div>
                </div>
                <div class="col-xs-3">

                    <div class="headline-news-list">
                        <div class="media">
                            <div class="media-body">
                                <h4 class="media-heading color_qiyelan font_size16" style="font-weight: normal"><a href="{$rs[3]['url']}">{$rs[3]['title']}</a></h4>
                                <div class="media-content  color_777 ">{$rs[3]['remark']}</div>
                            </div>
                        </div>
                        <div class="media">
                            <div class="media-body">
                                <h4 class="media-heading color_qiyelan font_size16" style="font-weight: normal"><a href="{$rs[4]['url']}">{$rs[4]['title']}</a></h4>
                                <div class="media-content color_777">{$rs[4]['remark']}</div>
                            </div>
                        </div>
                        <div class="media">
                            <div class="media-body">
                                <h4 class="media-heading color_qiyelan font_size16" style="font-weight: normal"><a href="{$rs[5]['url']}">{$rs[5]['title']}</a></h4>
                                <div class="media-content color_777">{$rs[5]['remark']}</div>
                            </div>
                        </div>
                    </div>
                </div>
{/wz}

通过主键直接赋值：

{$rs[0]['title']}
主键从0开始 ，自动增长：如，0，1，2，3....
