Did you checked the HTML result from this markup? Does it seems to you all right?

I did not get the point "only one selectable". What exactly this means?

Kornfeld Eliyahu Peter 14-Dec-14 4:20am

I think OP means to enable to select only one answer - I think OP try to display questions with possible answers to choose from...

Tadit Dash (ତଡିତ୍ କୁମାର ଦାଶ) 14-Dec-14 4:32am

Yeah, ok. :)

Oh ok. So. You should use checked property, not group name.
