2.0 form: selected radio button value doesn't show up in iframe
I have created a 2.0 form. As the form is embedded on a non MTKO page and I needed the fields to be pre-filled, I have added form to a landing page and created an iFrame.
The issue is that I have a radio button question where I wanted to have one selected by default field. I can perfectly see the selection when I preview the form. I could also see it when I had added the form directly in Drupal. However since I have implemented the iFrame, it doesn't show up anymore. How can I fix that?
