   parse="inward"
   } 

<dl class="tabs contained">
     {discipline_3rd_order var_prefix="discipline_matrix"}
        {discipline_matrix:m_p_discipline var_prefix="mx_disipline_playa"}
          <dd  {if count == '1'}class="active"{/if}><a href="#simpleContained{url_title}">{mx_disipline_playa:discipline_short_name}</a></dd>
                    {/discipline_matrix:m_p_discipline}
                {discipline_3rd_order}
</dl>
