Get individual form collection elements ZF2 - php

Question

I need to use collections to make dynamic inputs, but needed to pull out the individual elements to integrate them into a Bootstrap layout.
Unfortunately I can't find any documented way of doing this.
Could someone help-me?
Here is my form: http://pastebin.com/JGy7JEJk Fieldset used in form:

public function renderCollection($element)
{
$return = '';
if (count($element->getMessages()) > 0) {
$return .= '<div class="form-group has-error">';
} else {
$return .= '<div class="form-group">';
}
foreach ($element->getIterator() as $field) {
$label = ($this->isView) ? '<strong>' . $element->getLabel() . '</strong>' : $element->getLabel();
$return .= '<label class="col-md-3 control-label">' . $label . '</label>';
$return .= '<div class="col-md-8" style="margin-bottom: 20px;">';
foreach ($field->getElements() as $inputs) {
$return .= '<div style="float: left; margin-right: 20px;">';
$return .= $inputs->getLabel();
$return .= $this->renderInput($inputs);
$return .= '<div style="min-width: 265px;">';
foreach ($inputs->getMessages() as $mensagem) {
$return .= "<span class='help-block'>" . $mensagem . "</span>";
}
$return .= '</div>';
$return .= '</div>';
}
$return .= '</div>';
$element->setLabel('');
}
$return .= '</div>';
return $return;
