Adding Form field dynamically in helper form Prestashop - prestashop-1.6

Question

I have a back office admin controller in which I am using the helper form in renderform() to generate a form and it is working form but I want a functionality to add a field in that form dynamically.

Answer 1

I have done this by helper list, while rendering the form I am returning a render list also, check renderAdditionalOptionsList() usage
public function renderForm() {
$id_citydelivery = (int) Tools::getValue('id_citydelivery');
$citydeliveryObj = new CityPortModel($id_citydelivery);
if (Validate::isLoadedObject($citydeliveryObj)) {
$_legends = $citydeliveryObj->legend;
$_legend_array = explode(',', $_legends);
foreach ($_legend_array as $_legend) {
$this->fields_value['legend_' . $_legend] = $_legend;
}
}
$temp = $this->fields_value;
$fields_form_1 = array(
'form' => array(
'legend' => array('title' => $this->l('Price and Delivery Destination Manager'), 'icon' => 'icon-cogs'),
