Hi,
Thanks for your feedback, we just fixed it, you'll just have to edit the file "YOUR WEBSITE\administrator\components\com_hikashop\views\product\tmpl\selection.php", and add these lines :
<td nowrap="nowrap">
<?php echo $this->productType->display('filter_product_type',$this->pageInfo->filter->filter_product_type); ?>
</td>
after these lines :
<td width="100%">
<?php echo JText::_('FILTER');?>:
<input type="text" id="hikashop_product_search" name="search" value="<?php echo $this->escape($this->pageInfo->search);?>" class="text_area" onchange="this.form.submit();" />
<button class="btn" onclick="this.form.submit();"><?php echo JText::_('GO'); ?></button>
<button class="btn" onclick="document.getElementById('hikashop_product_search').value='';this.form.submit();"><?php echo JText::_('RESET');?></button>
</td>
EDIT
You'll need more modifications to do that so you should just download the last package of Hikashop and install it.
