Answer 1

Try below code:
public function actionContact() {
$model = new ContactForm();
if ($model->load(Yii::$app->request->post()) && $model->validate()) {
$status = Yii::$app->mailer->compose()
->setTo($model->email_to)
->setFrom([$model->email_from => $model->email_from])
->setSubject($model->subject)
->setTextBody($model->message)
->send();
if ($status) {
Yii::$app->session->setFlash('success', 'Thank you for contacting us. We will respond to you as soon as possible.');
} else {
Yii::$app->session->setFlash('error', 'There was an error sending email.');
}
return $this->refresh();
} else {
return $this->render('contact', [
'model' => $model,
]);
}
}
You can also create a email_template directory under views folder and create template file in which you can set email template content.

Answer 2

you can use js or ajax to do the same.
1: Use jQuery:
I assume that you are using jQuery. So use ajax.
.......JS Cod........
/*I assume that you have your template data in an attribute like data-template-data=""*/
$('#select_template_id').chang(function(){
template=$(this).attr('data-template-data');
$('#template_edit_box').val(template);
});
