I don’t understand the concept of radio buttons
What part doesn’t make sense to you?
Radio inputs are a form value where only one of the group can be selected.
When you see things like this, you’re seeing radio buttons.
Back in the olden days, when car radios had mechanical dials, before digital, radios had programable buttons. They were hard to push, but they would physically move the dial, if you pressed one, the button would go down and stay down and move the radio dial. If you press a new one, the old one would pop up and the new one would go down and move the dial.you could only have one station selected at a time.
Thanks… It is much clearer now. I appreciate a lot
