+/**
+ * ToggleButtons are buttons that have a state (‘on’ or ‘off’) that is represented by a
+ * Boolean value. Like other {@link OO.ui.ButtonWidget buttons}, toggle buttons can be
+ * configured with {@link OO.ui.IconElement icons}, {@link OO.ui.IndicatorElement indicators},
+ * {@link OO.ui.TitledElement titles}, {@link OO.ui.FlaggedElement styling flags},
+ * and {@link OO.ui.LabelElement labels}. Please see
+ * the [OOjs UI documentation][1] on MediaWiki for more information.
+ *
+ *     @example
+ *     // Toggle buttons in the 'off' and 'on' state.
+ *     var toggleButton1 = new OO.ui.ToggleButtonWidget( {
+ *         label: 'Toggle Button off'
+ *     } );
+ *     var toggleButton2 = new OO.ui.ToggleButtonWidget( {
+ *         label: 'Toggle Button on',
+ *         value: true
+ *     } );
+ *     // Append the buttons to the DOM.
+ *     $( 'body' ).append( toggleButton1.$element, toggleButton2.$element );
