I have a configurable product and I want to show all available options at once (no dropdown). I can use the ‘size=‘ attribute on the select html element to achieve this. However, to get this working correctly I need to count the number of options available in the dropdown box.

Is there any way to count the number of options available? Here’s my current code from configurable.phtml .

<?php $  _product    = $  this->getProduct(); $  _attributes = Mage::helper('core')->decorateArray($  this->getAllowAttributes()); $  _jsonConfig = $  this->getJsonConfig(); $  _renderers = $  this->getChild('attr_renderers')->getSortedChildren(); ?> <?php if ($  _product->isSaleable() && count($  _attributes)):?>     <dl>     <?php foreach($  _attributes as $  _attribute): ?>         <?php         $  _rendered = false;         foreach ($  _renderers as $  _rendererName):             $  _renderer = $  this->getChild('attr_renderers')->getChild($  _rendererName);             if (method_exists($  _renderer, 'shouldRender') && $  _renderer->shouldRender($  _attribute, $  _jsonConfig)):                 $  _renderer->setProduct($  _product);                 $  _renderer->setAttributeObj($  _attribute);                 echo $  _renderer->toHtml();                 $  _rendered = true;                 break;             endif;         endforeach;          if (!$  _rendered):         ?>         <div class="option-view">             <dt><label class="required"><em>*</em><?php echo $  _attribute->getLabel() ?></label></dt>             <dd<?php if ($  _attribute->decoratedIsLast){?> class="last"<?php }?>>                 <div class="input-box">                     <select name="super_attribute[<?php echo $  _attribute->getAttributeId() ?>]" id="attribute<?php echo $  _attribute->getAttributeId() ?>" class="required-entry super-attribute-select" size="5">                         <option><?php echo $  this->__('Choose an Option...') ?></option>                       </select>                   </div>             </dd>          </div>         <?php endif; ?>     <?php endforeach; ?>     </dl>     <script type="text/javascript">         var spConfig = new Product.Config(<?php echo $  _jsonConfig ?>);     </script>     <?php echo $  this->getChildHtml('after') ?> <?php endif;?>
