Radio Button Group By Key

Hi,

I have a requirement like i am in need to disable the rest of the options in the radio buttton group to be disabled when one among them is selected. In one of the thread in the same forum i read about disabling the input field and it was in the case if the options are having a input field each. but in my case the options are based on the domain value of the attribute i have assigned to the radio button group. In such case what is the way to disable the other options.

Thanks,
