    {pboot:nav num=10 parent={sort:tcode}}
        {pboot:if([nav:i]==1)}
            {pboot:2if('{sort:scode}'=='{sort:tcode}')}
                <a href="{sort:toplink}" class="btn btn-info mb-2">全部 <span class="badge badge-light">{sort:toprows}</a>
            {2else}
                <a href="{sort:toplink}" class="btn btn-light mb-2">全部 <span class="badge btn-info">{sort:toprows}</a>
            {/pboot:2if}
        {/pboot:if}
        
        {pboot:if('[nav:scode]'=='{sort:scode}')}
            <a href="[nav:link]" class="btn btn-info mb-2">[nav:name] <span class="badge badge-light">[nav:rows]</span></a>
        {else}
            <a href="[nav:link]" class="btn btn-light mb-2">[nav:name] <span class="badge btn-info">[nav:rows]</span></a>
