How to use subforms in Zend Framework2

Question

Is there a way how I can use zend subforms in Zend Framework2. When I did a search in the internet I have landed upon many examples showing how to use zend subforms but using Zend Framework1.

In case if somebody has a link/example where one can go through a basic example, would be great.

Any information is appreciated.

Because Zend\Form is tree structure, you could add another form into your form with a form name. Such like this:

$form = new \Zend\Form\Form();
$form->add(array(
    'name' => 'username',
    'type'  => 'Zend\Form\Element\Text',
));

$subForm = new \Zend\Form\Form();
$subForm->setName('subform');
$subForm->add(array(
    'name' => 'email',
    'type'  => 'Zend\Form\Element\Text',
));

$form->add($subForm);

$form->prepare();

$helper = new Zend\Form\View\Helper\FormText();
echo $helper($form->get('username')); //<input type="text" name="username" value="">
echo $helper($form->get('subform')->get('email')); //<input type="text" name="subform[email]" value="">

Notice that the "subform" input name will be add form name as prefix automatic.
