f:form.radio¶
This ViewHelper allows you to create a radio button element for use in an HTML form. Radio button fields are usually
used in groups, and only a single radio button in a group may be active at one time. A multiple selection - like the one
we see when using checkboxes - isn’t possible with radio buttons.
