How to open a Modal from TbButtonGroup

[danilo di moia]

Hi, first of all I don't know if this is the right place to post this question.... but I would like to know if it possible to open a modal dialog from an item in TbButtonGroup.

I've tried this code:

 

 <?php $this->widget('bootstrap.widgets.TbButtonGroup', array(
        'size' => 'mini',
         'htmlOptions'=>array('class'=>'pull-right'),
        'buttons'=>array(
            array('label'=>t('Actions'), 'url'=>'#'),
            array('items'=>array(
                array('label'=>t('Open Model'),'url'=>'#','htmlOptions'=>array('data-toggle'=>'modal','data-target'=>'#myModal')),
     
            )), 
        ),  
    )); ?>

 'htmlOptions' option is not rendered inside <a > link. Any hint, please?

Cheers
