CakePHP - Have the label and form in Form helper on different line


I'm using this code now

echo $form->input('username');

How do I make sure the label shows up on a different line than the input field?

I managed to imitate what I'm trying to do, just want to make sure that I'm using it the right way.

echo $form->label('username', 'Username');

echo $form->input('username', array('label' => false));
