          &lt;option selected="selected"&gt;Carta di Identità&lt;/option&gt;
          &lt;option&gt;Passaporto&lt;/option&gt;
          &lt;option&gt;Patente di Guida&lt;/option&gt;
      &lt;/c:when&gt;
      &lt;c:when test="${iUserInfo.identification_card_type}==1"&gt;
          &lt;option&gt;Carta di Identità&lt;/option&gt;

          &lt;option&gt;Patente di Guida&lt;/option&gt;
      &lt;/c:when&gt;
      &lt;c:when test="${iUserInfo.identification_card_type}==2"&gt;
          &lt;option&gt;Carta di Identità&lt;/option&gt;
          &lt;option&gt;Passaporto&lt;/option&gt;
          &lt;option selected="selected"&gt;Patente di Guida&lt;/option&gt;
      &lt;/c:when&gt;
      &lt;c:otherwise&gt;
          &lt;option&gt;Scegli...&lt;/option&gt;
          &lt;option&gt;Carta di Identità&lt;/option&gt;
          &lt;option&gt;Passaporto&lt;/option&gt;
          &lt;option&gt;Patente di Guida&lt;/option&gt;
      &lt;/c:otherwise&gt;
  &lt;/c:choose&gt;
