/**
 * ButtonSelectWidget is a {@link OO.ui.SelectWidget select widget} that contains
 * button options and is used together with
 * OO.ui.ButtonOptionWidget. The ButtonSelectWidget provides an interface for
 * highlighting, choosing, and selecting mutually exclusive options. Please see
 * the [OOjs UI documentation on MediaWiki] [1] for more information.
 *
 *     @example
 *     // Example: A ButtonSelectWidget that contains three ButtonOptionWidgets
 *     var option1 = new OO.ui.ButtonOptionWidget( {
 *         data: 1,
 *         label: 'Option 1',
 *         title: 'Button option 1'
 *     } );
 *
 *     var option2 = new OO.ui.ButtonOptionWidget( {
 *         data: 2,
 *         label: 'Option 2',
 *         title: 'Button option 2'
 *     } );
 *
 *     var option3 = new OO.ui.ButtonOptionWidget( {
 *         data: 3,
 *         label: 'Option 3',
 *         title: 'Button option 3'
 *     } );
 *
 *     var buttonSelect=new OO.ui.ButtonSelectWidget( {
 *         items: [ option1, option2, option3 ]
 *     } );
 *     $( 'body' ).append( buttonSelect.$element );
