    <option value="<?php echo $category->id?>" <?php echo $session->get('categorySearch')==$category->id && $preserve?" selected ":"" ?> ><?php echo $category->name?></option>
    <?php if(!empty($category->subcategories)){?>
    <?php foreach($category->subcategories as $subCat){?>
    <option value="<?php echo $subCat->id?>" <?php  echo $session->get('categorySearch')==$subCat->id && $preserve?" selected ":"" ?> >-- <?php echo $subCat->name?></option>
    <?php }?>
      <?php }?>

 <?php }?>
