Hi BICKY, welcome to the forum.

Doesn’t this wiki article help you?

As you are using an active form, the view code will be like this:




<div class="row">

	<?php echo $form->labelEx($model,'subject'); ?>

	<?php echo $form->dropDownList($model,'subject',

		CHtml::listData(masterSubject::model()->findAll(), "id", "subject"),

		array(

			'empty'=>'select subject',

			'ajax'=>array(

				'type'=>'POST',

				'url'=>CController::createUrl('myController/getTeachers'),

				'update'=>'#'.CHtml::activeId($model, 'teacher')

			),

		)) ?>

	<?php echo $form->error($model,'subject'); ?>

</div>


<div class="row">

	<?php echo $form->labelEx($model,'teacher'); ?>

	<?php echo $form->dropDownList($model,'teacher',

		array(), // initially empty

		array('empty'=>'select teacher')) ?>

	<?php echo $form->error($model,'teacher'); ?>

</div>
