Check the ajax helper observeField. An ilustrative non-tested example: [form view] <?php echo $form->select('Model.select1', array('A', 'B')); ?> <select id="select2"> </select> <?php echo $form->observeField('ModelSelect1', array( 'update'=> 'select2' , 'url'=> '/your/action' )); ?> [your controller] function action() { if( !empty($this->data) ) { if( $this->data['Model']['select1'] == 'A' ) $options= array('C', 'D'); elseif( $this->data['Model']['select1'] == 'B' ) $options= array('E', 'F'); } $this->set(compact('options')); } [you action-view] <?php foreach($options as $option): ?> <option id="<?php echo key($option); ?>"> <?php echo current($option); ?> </option> <?php endforeach; ?> I hope it helps.
