Radio buttons are similar to checkboxes, but only one radio button can be active.

Selecting one deselects the other ones.

By setting one as checked, you make sure one is always selected.

<input type="radio" name="category" value="article" checked />
<input type="radio" name="category" value="tutorial" />
<input type="radio" name="category" value="news" />

Since only one is active at a time, in the POST request you’ll use the get() method of the FormData instance to retrieve the value selected.
