Panorama

The Panorama widget is a full-screen widget that allows you to arrange items on a long horizontal canvas split into several views. Each view contains several items, and an end user navigates the views with the swipe gesture. The Panorama is often used as a navigation map on the first page of an application.

You can create the widget using one of the following approaches.

  • jQuery

    HTML
    CSS
    JavaScript
    <div id="panorama"></div>
    #panorama {
        height: auto;
        position: absolute;
        top: 0; 
        bottom: 0;
        width: 100%;
    }
    var panoramaItems = [{
        title: "Main courses",
        text: "First and second courses of a meal"
    }, {
        title: "Seafood",
        text: "Seafood: ocean and sea"
    },
        // . . .
    ];
    $(function () {
        $("#panorama").dxPanorama({
            items: panoramaItems,
            title: "Online Menu",
            backgroundImage: {
                url: '/here/goes/your/image.png',
                height: 600,
                width: 800
            }
        });
    });
  • Angular

    HTML
    JavaScript
    <dx-panorama
        [items]="panoramaItems"
        title="Online Menu">
        <dxo-background-image
            url="/here/goes/your/image.png"
            [height]="600"
            [width]="800">
        </dxo-background-image>
    </dx-panorama>
    export class AppComponent {
        panoramaItems = [
            // ...   
        ];
    }
  • AngularJS

    HTML
    JavaScript
    <div ng-controller="DemoController">
        <div id="panorama" dx-panorama="{
            items: panoramaItems,
            title: 'Online Menu',
            backgroundImage: {
                url: '/here/goes/your/image.png',
                height: 600,
                width: 800
            }
        }"></div>
    </div>
    angular.module('DemoApp', ['dx'])
        .controller("DemoController", function ($scope) {
            $scope.panoramaItems = [
                // ...   
            ];
        });
  • Knockout

    HTML
    JavaScript
    <div id="panorama" data-bind="dxPanorama: {
        items: panoramaItems,
        title: 'Online Menu',
        backgroundImage: {
            url: '/here/goes/your/image.png',
            height: 600,
            width: 800
        }
    }"></div>
    var viewModel = {
        panoramaItems: [
            // ...
        ]
    };
    ko.applyBindings(viewModel);

Note that DevExtreme widgets require you to link the jQuery library to your application. If you use the Knockout or AngularJS approach, the Knockout or AngularJS library is also required. For detailed information on linking these libraries to your project, refer to the topics in the Installation section.
