I have this implementation of CHtml:
<?=CHtml::dropDownList(‘id_sistema’, $Proveedor[0][‘id_sistema’],CHtml::listData(Sistemas::model()->findAll(),‘sistema_id’, ‘sistema_nombre’),array(‘empty’ => ‘Selecciona un sistema…’),array(‘class’=>‘form-control chosen-select’));?>
But is so weird that is not recognizing the ‘form-control’ css class. I have read several times the documentation and I can not find de issue.
I someone have any idea, I will appreciate it!
