The only "form" I see on that site is a group of radio buttons. The only thing special I see is that the radio buttons possibly have custom CSS applied to change their appearance. See this example: https://www.w3school...om_checkbox.asp
Or, it could be that they are "plain" radio buttons at all. They also look similar to JQueryUI radio buttons: https://jqueryui.com...dio/#radiogroup
Except that the example above has the button and label within a "button" that changes background color based on the selected state of the radio button.
Or, if there is more to the form than the radio buttons, you will need to point it out. That was the only thing I saw as field input on that page.Go to the full post
