See the following code example:

$state = $this->createWidget('ext.jquery-cascade.jQueryCascade');

// dropDownList($id, $selected, $data, $htmlOptions = array(), $source, $cascaded)
echo $state->dropDownList('stateId',
    '',
    CHtml::listData(State::model()->findAll(), 'id', 'name'),
    '',
    CController::createUrl('city/list'),
    'cityId'
);

The function which serves the data needed:

public function actionList()
{
    if (Yii::app()->request->isAjaxRequest) {
        $state = State::model()->findByPk($_GET['selected']);
        $cities = array();

        foreach ($state->cities as $city) {
            $cities[] = array('label' => $city->name, 'value' => $city->id);
        }

        echo json_encode($cities);
        Yii::app()->end();
    } else {
        throw new CHttpException(400, 'Invalid request.');
    }
}
