Changing modal size

Yii 1.1 General Discussion

I have a modal that I want the size to be large but when I add the tag


'size'=>'large'

on the button that generates the modal it makes the button large and the modal stays the same size. Also Tried to add the same tag inside the modal like this


<?php $this->beginWidget(

    'booster.widgets.TbModal',

    array(['id' => 'availability-modal',

'size'=>'large'])

);?>

It returns


Property "TbModal.0" is not defined.

Is there another way to change the modal size?

Thanks
