Customize Item Appearance

To customize views in the MultiView, define a custom template for them. For Angular, AngularJS, and Knockout apps, DevExtreme provides the dxTemplate markup component. The following code shows how to use dxTemplate to define a template for MultiView views.

Angular
HTML
TypeScript
<dx-multi-view
    [dataSource]="multiViewItems"
    itemTemplate="items">
    <div *dxTemplate="let item of 'items'">
        <div style="margin:25px;">
            <h1>{{item.title}}</h1>
            <div style="text-align:left;" *ngFor="let dataItem of item.dataArray">
                <p>{{dataItem.propertyKey}}: <b>{{dataItem.propertyValue}}</b></p>
            </div>
        </div>
    </div>
</dx-multi-view>
import { DxMultiViewModule } from "devextreme-angular";
import DataSource from "devextreme/data/data_source";
// ...
export class AppComponent {
    multiViewItems = new DataSource({
        store: [{
            title: "Personal Data",
            data: {
                firstName: "John",
                lastName: "Smith",
                birthYear: 1986
            }
        }, {
            title: "Contacts",
            data: {
                phone: "(555)555-5555",
                email: "John.Smith@example.com"
            }
        },
        // ...
        ],
        // Brings each item of the array to a specific structure
        map: (itemData) => {
            itemData.dataArray = Object.keys(itemData.data).map((key) => {
                return {
                    propertyKey: key,
                    propertyValue: itemData.data[key]
                }
            });
            return itemData;
        }
    });
}
@NgModule({
    imports: [
        // ...
        DxMultiViewModule
    ],
    // ...
})
AngularJS
HTML
JavaScript
<div ng-controller="DemoController" style="height: 100%;">
    <div dx-multi-view="{
        dataSource: multiViewItems,
        itemTemplate: 'item'
    }" dx-item-alias="itemObj">
        <div data-options="dxTemplate: { name: 'item' }">
            <div style="margin:25px;">
                <h1>{{ itemObj.title }}</h1>
                <div style="text-align:left;" ng-repeat="(key, value) in itemObj.data">
                    <p>{{ key }}: <b>{{ value }}</b></p>
                </div>
            </div>
        </div>
    </div>
</div>
angular.module('DemoApp', ['dx'])
    .controller('DemoController', function ($scope) {
        $scope.multiViewItems = [{
            title: "Personal Data",
            data: {
                firstName: "John",
                lastName: "Smith",
                birthYear: 1986
            }
        }, {
            title: "Contacts",
            data: {
                phone: "(555)555-5555",
                email: "John.Smith@example.com"
            }
        },
        // ... 
        ];
    });
NOTE
The dx-item-alias directive specifies the variable that is used to access the item object.
Knockout
HTML
JavaScript
<div data-bind="dxMultiView: { dataSource: multiViewItems, itemTemplate: 'item' }">
    <div data-options="dxTemplate: { name: 'item' } ">
        <div style="margin:25px;">
            <h1 data-bind="text: title"></h1>
            <div style="text-align:left;" data-bind="foreach: dataArray">
                <p><span data-bind="text: propertyKey">
                </span>: <b data-bind="text: propertyValue"></b></p>
            </div>
        </div>
    </div>
</div>
var viewModel = {
    multiViewItems: new DevExpress.data.DataSource({
        store: [{
            title: "Personal Data",
            data: {
                firstName: "John",
                lastName: "Smith",
                birthYear: 1986
            }
        }, {
            title: "Contacts",
            data: {
                phone: "(555)555-5555",
                email: "John.Smith@example.com"
            }
        },
        // ...
        ],
        // Brings each item of the array to a specific structure
        map: function (itemData) {
            itemData.text = itemData.title;
            itemData.dataArray = $.map(itemData.data, function (value, key) {
                return {
                    propertyKey: key,
                    propertyValue: value
                }
            });
            return itemData;
        }
    })
};

ko.applyBindings(viewModel);

If you use jQuery alone, use DOM manipulation methods to combine the HTML markup for items. To apply this markup, use the itemTemplate callback function as shown in the following code.

JavaScript
var multiViewItems = [{
    title: "Personal Data",
    data: {
        firstName: "John",
        lastName: "Smith",
        birthYear: 1986
    }
}, {
    title: "Contacts",
    data: {
        phone: "(555)555-5555",
        email: "John.Smith@example.com"
    }
},
// ... 
];

$(function() {
    $("#multiViewContainer").dxMultiView({
        dataSource: multiViewItems,
        itemTemplate: function (itemData, itemIndex, itemElement) {
            var mainContainer = $("<div style='margin:25px;'>");
            mainContainer.append("<h1>" + itemData.title + "</h1>");

            var info = $("<div style='text-align:left;'>");
            for (var field in itemData.data) {
                info.append("<p>" + field + ": <b>" + itemData.data[field] + "</b></p>");
            }
            mainContainer.append(info);
            itemElement.append(mainContainer);
        }
    });
});

You can also customize an individual view. For this purpose, declare a template for this view as a script and pass its id to the template field.

HTML
JavaScript
<script id="individualTemplate" type="text/html">
    <!-- ... -->
</script>
var multiViewItems = [
    { text: "Personal Data" },
    { text: "Contacts", template: $('#individualTemplate') },
    { text: "Address" }
];

In addition, you can use a 3rd-party template engine to customize widget appearance. For more information, see the 3rd-Party Template Engines article.
