How to validate radio button in magento?

问题

In my custom module I have a form which has radio buttons.

When I click the submit button it does not validate the radio button.

How to validate that using the Magento default validate class.

Thanks

use validate-one-required on the last radio/checkbox in the group

Validation works, but to show error message you can't use any wrappers. Just

 <label> and <input>
