It is dependend from the numbers of incoming variables, as they have to be named in the proper way. For the case at hand that means that features are given like this features-1.selected_quantity features-2.selected_quantity Obviously you have to render the form fields accordingly. Unfortunately I'm not sure right now how that happens exactly, because the code above is validating some JS-generated forms. But AFAIK using e.g. fieldset with feature-widgets and passing an proper array of dicts to them should render the form correctly.
