ciao sto cercando di themizzare il file che mi personalizza il blocco dei filtri esposti, all'interno ho qualcosa del genere:

<?php
// $Id: views-exposed-form.tpl.php,v 1.4.4.1 2009/11/18 20:37:58 merlinofchaos Exp $
/**
* @file views-exposed-form.tpl.php
*
* This template handles the layout of the views exposed filter form.
*
* Variables available:
* - $widgets: An array of exposed form widgets. Each widget contains:
* - $widget->label: The visible label to print. May be optional.
* - $widget->operator: The operator for the widget. May be optional.
* - $widget->widget: The widget itself.
* - $button: The submit button for the form.
*
* @ingroup views_templates
*/
?>
<?php if (!empty($q)): ?>
  <?php
    // This ensures that, if clean URLs are off, the 'q' is added first so that
    // it shows up first in the URL.
    print $q;
  ?>
<?php endif; ?>
<div class="views-exposed-form">
  <div class="views-exposed-widgets clear-block">
    <?php foreach($widgets as $id => $widget): ?>
      <div class="views-exp-<?php print $widget->id; ?>">
        <?php if (!empty($widget->label)): ?>
          <label for="<?php print $widget->id; ?>">
            <?php print $widget->label; ?>
          </label>
        <?php endif; ?>
        <?php if (!empty($widget->operator)): ?>
          <div class="views-operator">
            <?php print $widget->operator; ?>
          </div>
        <?php endif; ?>
        <div class="views-widget">
          <?php print $widget->widget; ?>
        </div>
      </div>

    <?php endforeach; ?>
    <div class="views-exposed-widget">
      <?php print $button ?>
    </div>
  </div>
</div>

Io ho bisogno di raggruppare i vari filtri esposti con degli id, come posso fare?
