  I didn't know that one, so i give it you ...
  
  I needed a way to display a separator after all link in an extmenu except the last one....
  
  ... and you can do it in a quite simple way with Smarty
  indeed
  
  sample use
  

  Code

  <ul>
  <!--[foreach from=$items key='myId' item='item' name='foo']-->
    <li>
    <!--[if $smarty.foreach.foo.first]--> First <!--[/if]-->
      <!--[$item.label]-->
    <!--[if $smarty.foreach.foo.last]--> Last<!--[/if]-->
    </li>
  <!--[/foreach]-->
  </ul>

  Also useful for comma separated lists:
  

  Code

  <ul>
  <!--[foreach from=$items key='key' item='item' name='foo']-->
    <li>
      <!--[$item.label]-->
      <!--[if $smarty.foreach.foo.last neq true]-->, <!--[/if]-->
    </li>
  <!--[/foreach]-->
  </ul>

  
  
  or a CSS class handling of the first and last elements:
  

  Code

  <ul>
  <!--[foreach from=$items key='key' item='item' name='foo']-->
    <!--[assign var='cssClass' value='']-->
    <!--[if $smarty.foreach.foo.first neq true]-->
      <!--[assign var='cssClass' value='first']-->
    <!--[elseif $smarty.foreach.foo.last neq true]-->
      <!--[assign var='cssClass' value='last']-->
    <!--[/if]-->
  
    <li<!--[if $cssClass neq '']--> class="<!--[$cssClass]-->"<!--[/if]-->>
      <!--[$item.label]-->
    </li>
  <!--[/foreach]-->
  </ul>
