DJ Catalog2组件具有用于在产品说明中插入自定义字段的插件。 在标准customfileds表中-在产品描述下-在customfield多色中选择-这是
<span class="djc_cartattr_color">
<span class="djc_cartattr_color-bg" style="background-image: url('/media/djcatalog2/images/colors/image.png');"></span>
<span class="djc_cartattr_color-name">Name</span></span>
这是用于显示属性的文件代码：

如果我尝试通过插件（使用{djc2customfield color}代码）向商品说明添加一个属性，则只有
<span class="djc_attribute color_pr__ba">
<span class="djc_attribute-value">atribute value 1, atribute value 2</span>
</span>
未将图像分配给属性值。
在产品说明中显示属性的代码为：

我想使用layout =“ divs”。 我想我需要更改代码

但是我不知道如何。有人可以帮我这个吗？
