Zend_Form - Array based elements?

Question

Using Zend_Form, how would I create form elements like this:

Answer 1

I contend that setBelongsTo is of substandard quality, as one is unable to set default values. And so, at the present time, there's no reasonable way to achieve your objective.

Answer 2

You can either use subforms:

$form = new Zend_Form();

$subForm = new Zend_Form_SubForm();
$subForm->addElement('Text', '1')
        ->addElement('Text', '2');

$form->addSubForm($subForm, 'element');

Or you should also be able to use setBelongsTo() on the form elements (untested):

$form = new Zend_Form();
$form->addElement('Text', '1', array('belongsTo' => 'element'))
     ->addElement('Text', '2', array('belongsTo' => 'element'));
