elements,
like “text” or “select”, and they have the same flexibility as
Zend_Form, including the ability to specify
decorators
for complex elements:

public function formAction()
{
    $form = new pm_Form_Simple();
    $form->addElement('text', 'exampleText', [
        'label' => 'Example Text',
        'value' => 'Default value',
        'required' => true,
    ]);
}
