Zend2 Form - set attributes to options in select element

Question

I wonder how to add some attributes to select's options in Zend 2. My form element looks like this:

$this->add(array(

        'type' => 'Zend\Form\Element\Select',

        'name' => 'brand_name',

        'options' => array(

            'label' => 'Choose brand',

            'value_options' => $this->getBrands(),

        ),

    ));

So it's populate select looking similar to this:

<select name="brand_name"><option value="1">aaaa</option></select>

But I want to achieve something like this:

<select name="brand_name"><option value="1" class="test">aaaa</option></select>

And the classes should be different, depends on particular option. Is it possible? Why am I trying this? I need to add jquery plugin - chained which needs classes for options.

I've found a solution, array of parent select value_options should look like this:

foreach ($data as $item) {
        $models[] = array(
          'label' => $item->model_name, 
          'attributes' => array('class' => $item->id_brand_list), 
          'value' => $item->id);
    }
