You can add template directives in Cards Advanced Formatting.

This page uses TAGS column which contains comma separated values of the employee focus area. The Cards Body has the following HTML Expression:

{if TAGS/}
    <ul class="a-tags">
    {loop "," TAGS/}
 	    <li class="a-tag">&APEX$ITEM.</li>
    {endloop/}
    </ul>
{endif/}

If TAGS column value not null, the loop directive takes a value, in this case the TAGS comma separated value and splits it up into a list. The special symbol APEX$ITEM takes on the value of the current list item value.
