Magento core/html_select: Set option class

Question

Magento offers a function to generate a select from the backend: https://magently.com/blog/dropdown-selects-in-magento/

$select = $this->getLayout()->createBlock( 'core/html_select' )
 ->setName( 'addresses' )
 ->setOptions( $options );

This will give me something like this:

<select name="addresses">
 <option value="address1">address1</option>
 <option value="address2">address2</option>
</select>

but I want to set a class for the options:

<select name="addresses">
 <option value="address1" class="a">address1</option>
 <option value="address2" class="b">address2</option>
</select>

My options look like this:

$options[] = array(
 'value' => $address->getId(),
 'label' => $address->format( 'oneline' ),
 'parvw' => $address->getParvw()
);

parvw is the class parameter for the option

How can I set the class options?

• harri: Not sure how to do that with that function. I can think of a few workarounds that may be of use tho: If the purpose is to style them you can use css like:option[value=_address1] or jquery $('option > select > option[value="address1"]'). Or just a for each loop like: <?php $select = '<select name="addresses">'; foreach ($options as $option) { $select .= '<option value="' . $option['value'] . '" class="' . $option['parvw'] . '">' . $option['value'] . '</option>'; } $select .= '</select>'; ?>

Magento allow us to add additional params to the options of a select.

Here is how you need to modify your options:

$options[] = array(
 'value' => $address->getId(),
 'label' => $address->format( 'oneline' ),
 'params' => array ('class' => 'yourclass1')
);
$options[] = array(
 'value' => $address->getId(),
 'label' => $address->format( 'oneline' ),
 'params' => array ('class' => 'yourclass2')
);
