How to add class and id attributes to lithium form helper?

Question

I'm using the Form Helper in Lithium and wonder how to add the HTML attributes class and id to the output of $this->form->create();? I want to set these attributes on the form element.

Answer 1

As intuitive as $this->form->create(null, ['class' => 'foo', 'id' => 'bar'])

NB: replace null with $something if you are binding an object to the form.
