                <?php foreach($attributes as $attribute): ?>
                    <ul><li><?php echo $attribute['label']; ?></li></ul>
                     <select name="super_attribute[<?php echo $attribute['attribute_id'] ?>]" id="attribute<?php echo $attribute['attribute_id'] ?>">
                        <option> <?php echo $this->__('Choose an option') ?></option>
                        <?php $values = $attribute['values']; ?>
