Could you share us the website link where that radio button is?
Currently, we do not have that design, but you can check our widgets page for the list of radio buttons that you can use: http://widgets.jotform.com/search/radio.
You can also use a Dropdown field then conditional logic to show the "Radio buttons" instead.
I hope that helps.
