/**
+ * A {@link Ext.form.FieldContainer field container} which has a specialized layout for arranging
+ * {@link Ext.form.field.Radio} controls into columns, and provides convenience {@link Ext.form.field.Field}
+ * methods for {@link #getValue getting}, {@link #setValue setting}, and {@link #validate validating} the
+ * group of radio buttons as a whole.
+ *
+ * # Validation
+ *
+ * Individual radio buttons themselves have no default validation behavior, but
+ * sometimes you want to require a user to select one of a group of radios. RadioGroup
+ * allows this by setting the config `{@link #allowBlank}:false`; when the user does not check at
+ * one of the radio buttons, the entire group will be highlighted as invalid and the
+ * {@link #blankText error message} will be displayed according to the {@link #msgTarget} config.</p>
+ *
+ * # Layout
+ *
+ * The default layout for RadioGroup makes it easy to arrange the radio buttons into
+ * columns; see the {@link #columns} and {@link #vertical} config documentation for details. You may also
+ * use a completely different layout by setting the {@link #layout} to one of the other supported layout
+ * types; for instance you may wish to use a custom arrangement of hbox and vbox containers. In that case
+ * the Radio components at any depth will still be managed by the RadioGroup's validation.
+ *
+ * # Example usage
+ *
+ * @example
+ * Ext.create('Ext.form.Panel', {
+ * title: 'RadioGroup Example',
+ * width: 300,
+ * height: 125,
+ * bodyPadding: 10,
+ * renderTo: Ext.getBody(),
+ * items:[{
+ * xtype: 'radiogroup',
+ * fieldLabel: 'Two Columns',
+ * // Arrange radio buttons into two columns, distributed vertically
+ * columns: 2,
+ * vertical: true,
+ * items: [
+ * { boxLabel: 'Item 1', name: 'rb', inputValue: '1' },
+ * { boxLabel: 'Item 2', name: 'rb', inputValue: '2', checked: true},
+ * { boxLabel: 'Item 3', name: 'rb', inputValue: '3' },
+ * { boxLabel: 'Item 4', name: 'rb', inputValue: '4' },
+ * { boxLabel: 'Item 5', name: 'rb', inputValue: '5' },
+ * { boxLabel: 'Item 6', name: 'rb', inputValue: '6' }
+ * ]
+ * }]
+ * });
