OO.ui.BookletLayout

Extends

Constructor

new OO.ui.BookletLayout([config]) #

BookletLayouts contain page layouts as well as an outline that allows users to easily navigate through the pages and select which one to display. By default, only one page is displayed at a time and the outline is hidden. When a user navigates to a new page, the booklet layout automatically focuses on the first focusable element, unless the default setting is changed. Optionally, booklets can be configured to show controls for adding, moving, and removing items.

Example

// Example of a BookletLayout that contains two PageLayouts.

    function PageOneLayout( name, config ) {
        PageOneLayout.super.call( this, name, config );
        this.$element.append( '<p>First page</p><p>(This booklet has an outline, displayed on ' +
        'the left)</p>' );
    }
    OO.inheritClass( PageOneLayout, OO.ui.PageLayout );
    PageOneLayout.prototype.setupOutlineItem = function () {
        this.outlineItem.setLabel( 'Page One' );
    };

    function PageTwoLayout( name, config ) {
        PageTwoLayout.super.call( this, name, config );
        this.$element.append( '<p>Second page</p>' );
    }
    OO.inheritClass( PageTwoLayout, OO.ui.PageLayout );
    PageTwoLayout.prototype.setupOutlineItem = function () {
        this.outlineItem.setLabel( 'Page Two' );
    };

    const page1 = new PageOneLayout( 'one' ),
        page2 = new PageTwoLayout( 'two' );

    const booklet = new OO.ui.BookletLayout( {
        outlined: true
    } );

    booklet.addPages( [ page1, page2 ] );
    $( document.body ).append( booklet.$element );
