Custom form template within AdminModule

[ezzYY]

Hello

 

I would like to insert a custom template within the renderForm function of a AdminModule. Because the form heIper is not flexible enough for me. Need to add onClick methods, hidden fields etc. I already tried the following:

public function renderForm() {
    return $this->context->smarty->fetch(dirname(__FILE__) . '/../../templates/forms/field.tpl');
}

But I only get an blank page. Any suggestions?
