In this section, you will learn how to create radio buttons in dojo. For creating radio button you need "dijit.form.CheckBox". The radio button do some action on press. 

The RadioButton class is declared in the CheckBox.js file, hence you need dojo.require(dijit.form.CheckBox) for RadioButtons to work.

[Radio buttons are used when there is a list of two or more options that are mutually exclusive and the user must select exactly only one choice from a group of radio button. Click a non-selected radio button will deselect whatever other button was previously selected in the list.]

  dojo.require("dijit.form.*");
  </script>
  </head>
