回答1:

change your $htmlOptions to be like this:

$htmlOptions = array(
    'size' => '5',
    'multiple' => 'true',
    'options'=>array(45=>array('disabled'=>'disabled')),
);

45 here is a section_id

and if you want to find out how it's implemented you can take a look a this https://github.com/yiisoft/yii/blob/master/framework/web/helpers/CHtml.php#L2516
