Zend2: Outputting a single form element if its a radio button list?

Question

I have a radio button list with three options: daily, monthly, weekly. I want a way to access each one individually. For example:

echo $this->formElement($form->get('iteration'));

Will print out all three values, with their labels:

[ ] daily
[ ] monthly
[ ] weekly

I want a way to iterate over all the elements. Something like this:

foreach ($this->formElements($form->get('iteration') as $element)  {
    echo $this->formElement($element); 
}

But that doens't work. Any thoughts?

When you're using the Zend\Form\Element\Radio form element with multiple options, you can iterate over the options like this:

foreach ($form->get('iteration')->getValueOptions() as $option) {
    ...
}

But if you want to output the options separately, you'd need to create multiple Zend\Form\Element\Radio's.
