create custom Zend form element?

[Shawazi]

I have a test form made using Zend like this

$form = new Zend_Form();
$form->setAction($_SERVER['PHP_SELF'])
		 ->setMethod('post');

// Create and configure username element:
$username = $form->createElement('text', 'username');
$username->addValidator('alnum')
				 ->addValidator('regex', false, array('/^[a-z]+/'))
				 ->addValidator('stringLength', false, array(6, 20))
				 ->setRequired(true)
				 ->addFilter('StringToLower');

// Add elements to form:
$form->addElement($username)
		 ->addElement($password)
		 // use addElement() as a factory to create 'Login' button:
		 ->addElement('submit', 'login', array('label' => 'Login'));

What I need is to make some custom element that really is just a DIV with an ID and title (because I am making a field with JS that converts the DIV to proper inputs).

I have looked online for a way to create custom form elements but keep running into custom form error messages.

One possible solution is here:
http://www.nabble.com/Zend_Form-Custom-Elements-and-Input-type-file-td15620129.html

But it does not explain what goes in the test.php file to make it work - leaving me confused. If anyone has a helpful article on hand even, that would be great.
