Do it with javascript jquery… onchange event do ajax call, call a controller to return a renderPartial view and update the layer with another form.

Here is what you need: http://www.bitrepository.com/dynamic-dependant-dropdown-list-us-states-counties.html

But for the "yii way" you need to know basics, Antonio gave you the algorithm.

<div class="form">


<script>

 $("select").change(function () {

			alert('worked');

        });

        

</script>

<?php $form=$this->beginWidget('CActiveForm', array(

	'id'=>'imagens-form',

	'enableAjaxValidation'=>false,

)); ?>


	<p class="note">Fields with <span class="required">*</span> are required.</p>


	<?php echo $form->errorSummary($model); ?>


	

	

	<div class="row">

		<?php echo $form->dropDownList($model,'imagem',array('1','121','3')); ?>

	</div>


	<div class="row buttons">

		<?php echo CHtml::submitButton($model->isNewRecord ? 'Create' : 'Save'); ?>

	</div>


<?php $this->endWidget(); ?>


</div><!-- form -->

isnt working =/

Because <script> needs to be behind <select>… Or put:


$(document).ready(function() {

  // Handler for .ready() called.

});
