Zend Form - Add a <div> around the input element - twitter-bootstrap-3

Question

I'm using Zend Framework 2 Form to render my forms, and Bootstrap 3 to style them.
I want to use the Horizontal Form Layout as explained here:
Bootstrap 3 Forms tutorial
To do so, I need to add a div with appropriate classes around the input element; is there any easy way to add such div while adding the new element to the Form class? My element so far:
$this->add(array(
'name' => 'name',
'attributes' => array(
'type' => 'text',
'id' => 'contactName',
'maxlength' => '70',
'placeholder' => 'Your full name.',
'class' => 'form-control'
),
'options' => array(
'label' => 'Name: ',
'label_attributes' => array(
'class' => 'control-label col-xs-12 col-sm-2'
)
),
));
Can I add anything here to easily add <div class="col-xs-12 col-sm-10"></div> around the input element when I render it with <?php echo $this->formRow($this->form->get('name')); ?>?

Answer 1

I finally managed to solve the problem by creating a custom View Helper:
public function __invoke($element) {
echo '<div class="form-group">';
echo $this->view->formLabel($element);
echo '<div class="col-xs-12 col-sm-10">' . $this->view->formElement($element) . '</div>';
echo $this->view->formElementErrors($element);
echo '</div>';
}
Though I still wonder if there was another easier way to do that!
