DevExtreme Angular - Customize Item Appearance

To customize views in the MultiView, define an itemTemplate. In Angular and Vue, you can declare it in the markup. In React, you can use a rendering function (shown in the code below) or component.

Angular
HTML
TypeScript
<dx-multi-view
    [dataSource]="multiViewItems"
    itemTemplate="item">
    <div *dxTemplate="let content of 'item'">
        <div style="margin: 25px;">
            <h1>{{content.title}}</h1>
            <div style="text-align: left;">
                <p *ngFor="let key of getItemKeys(content.data)">
                    {{key}}: <b>{{content.data[key]}}</b>
                </p>
            </div>
        </div>
    </div>
</dx-multi-view>
import { DxMultiViewModule } from 'devextreme-angular';
// ...
export class AppComponent {
    multiViewItems = [{
        title: 'Personal Data',
        data: { firstName: 'John', lastName: 'Smith', birthYear: 1986 }
    }, {
        title: 'Contacts',
        data: { phone: '(555)555-5555', email: 'John.Smith@example.com' }
    }];
    getItemKeys (item) {
        return Object.keys(item);
    }
}
@NgModule({
    imports: [
        // ...
        DxMultiViewModule
    ],
    // ...
})
Vue
App.vue
<template>
    <DxMultiView
        :data-source="multiViewItems"
        item-template="item">
        <template #item="{ data }">
            <div :style="{ margin: '25px' }">
                <h1>{{data.title}}</h1>
                <div :style="{ textAlign: 'left' }">
                    <p v-for="key in getItemKeys(data.data)">
                        {{key}}: <b>{{data.data[key]}}</b>
                    </p>
                </div>
            </div>
        </template>
    </DxMultiView>
</template>
<script>

export default {
    components: {

    },
    data() {
        return {
            multiViewItems: [{
                title: 'Personal Data',
                data: { firstName: 'John', lastName: 'Smith', birthYear: 1986 }
            }, {
                title: 'Contacts',

React
App.js
import React from 'react';

class App extends React.Component {
    render() {
        return (

                dataSource={multiViewItems}
                itemRender={this.renderItem}

    renderItem(content) {

            <div style={{ margin: 25 }}>
                <h1>{content.title}</h1>

                            )}

        );
    }
}

export default App;

View Demo

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

jQuery
JavaScript
HTML
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 container = $("<div style='margin:25px;'>");
            container.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>");
            }
            container.append(info);
            itemElement.append(container);
        }
    });
});
<div id="multiViewContainer"></div>

You can also customize individual views. In Angular, Vue, and React, declare them using the dxItem component. When using jQuery, you can declare the views as scripts and reference them in the template option or assign a customization function straight to this option.

Angular
HTML
TypeScript
<dx-multi-view>
    <dxi-item text="Personal Data"></dxi-item>
    <dxi-item text="Contacts"></dxi-item>

import { DxMultiViewModule } from 'devextreme-angular';
// ...

    // ...

        // ...

    ],
    // ...

    <DxMultiView>
        <DxItem text="Personal Data" />
        <DxItem text="Contacts" />

import DxMultiView, { DxItem } from 'devextreme-vue/multi-view';

export default {
    components: {
        DxMultiView,
        DxItem
    }
};
</script>
React
App.js
import React from 'react';
import 'devextreme/dist/css/dx.common.css';
import 'devextreme/dist/css/dx.light.css';

import { MultiView, Item } from 'devextreme-react/multi-view';

class App extends React.Component {
    render() {
        return (
            <MultiView>
                <Item text="Personal Data"/>
                <Item text="Contacts"/>
            </MultiView>
        );
    }
}

export default App;
jQuery
JavaScript
HTML
$(function() {
    $("#multiViewContainer").dxMultiView({
        dataSource: [{
            text: "Personal Data",
            template: function() {
                return $("<p>").text("This is Personal Data View");
            }
        }, {
            text: "Contacts",
            template: $("#individualTemplate")
        }]
    });
});
<div id="multiViewContainer"></div>
<script id="individualTemplate" type="text/html">
    <p>This is Contacts View</p>
</script>

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