RadioButton
ion-radio
ion-radioA radio button is a button that can be either checked or unchecked. A user can tap
the button to check or uncheck it. It can also be checked from the template using
the checked property.
Use an element with a radio-group attribute to group a set of radio buttons. When
radio buttons are inside a radio group, exactly one radio button
in the group can be checked at any time. If a radio button is not placed in a group,
they will all have the ability to be checked at the same time.
See the Angular Forms Docs for more information on forms and input.
