Jet\Form_Field_RadioButton / Form_Field::TYPE_RADIO_BUTTON

Represents a form field for selecting an option from a list of options using an element called a radio button.

Attention! The form field is not a single radio button, but a set of radio buttons corresponding to the defined selection options.

You need to familiarize yourself with the options chapter.

The Jet\Form_Renderer_Field_Input_RadioButton renderer is used to display the form field itself.
