Letter Add Radio Button Groups For Free

The <input type="radio"> defines a radio button. Radio buttons are normally presented in radio groups (a collection of radio buttons describing a set of related options). Only one radio button in a group can be selected at the same time.

You group radio buttons by drawing them inside a container such as a Panel control, a GroupBox control, or a form. All radio buttons that are added directly to a form become one group. To add separate groups, you must place them inside panels or group boxes.

The radiogroup must have an accessible name either by a visible label referenced by aria-labelledby or has a label specified with aria-label . If elements provide additional information about the radio group, those elements are referenced by the radiogroup element with the aria-describedby property.

All radio groups require a group label of some kind. The classic method is using <fieldset> and <legend> . The ARIA method of role="radiogroup" and aria-labelledby can also be used.
