Yii add client side validation to a generated field

Hi,

If I were using jquery validation and I had a form in which some fields would be dynamically added upon clicking some button or an anchor tag, I would readily do something like


$('#elementid').rules('add',{required:true});

1.) Is there a way in yii client side validation (without using extensions) to do similar?

2.) What is the best jquery-validation based extension around if option 1 above is not possible?

Regards,

Z
