已筛选项目：
{openzc:filter item="active"}
<li>
        <a href="#">[field:filter_item/]</a>
        <div>
            {openzc:filter type="son"}

            <a href="[field:filter_link/]">Clear Filter</a>
        {/openzc:if}
</li>
{/openzc:filter｝

清除筛选条件：
{openzc:filter item="clear"}
<li>
    <a href="[field:filter_link/]">Clear Filter </a>
</li>
{/openzc:filter｝
