JavaScript/jQuery TabPanel - Customize Item Appearance

An item in the TabPanel UI component includes a tab and a view. For a minor customization of TabPanel items, you can define specific fields in item data objects. For example, the following code generates three items: the first has a badge, the second is disabled, the third has an icon.

jQuery
JavaScript
HTML
$(function() {
    $('#tabPanelContainer').dxTabPanel({
        items: [{
            title: 'Info',
            text: 'This is Info Tab',
            badge: 'New'
        }, {
            title: 'Contacts',
            text: 'This is Contacts Tab',
            disabled: true
        }, {
            title: 'Address',
            text: 'This is Address Tab',
            icon: 'home'
        }]
    });
});
<div id="tabPanelContainer"></div>
Angular
HTML
TypeScript
<dx-tab-panel
    [items]="tabPanelItems">
</dx-tab-panel>
import { DxTabPanelModule } from 'devextreme-angular';
// ...
export class AppComponent {
    tabPanelItems = [{
        title: 'Info',
        text: 'This is Info Tab',
        badge: 'New'
    }, {
        title: 'Contacts',
        text: 'This is Contacts Tab',
        disabled: true
    }, {
        title: 'Address',
        text: 'This is Address Tab',
        icon: 'home'
    }];
}
@NgModule({
    imports: [
        // ...
        DxTabPanelModule
    ],
    // ...
})
Vue
App.vue
<template>
    <DxTabPanel
        :items="tabPanelItems" />
</template>
<script>
import 'devextreme/dist/css/dx.light.css';

import DxTabPanel from 'devextreme-vue/tab-panel';

export default {
    components: {
        DxTabPanel
    },
    data() {
        return {
            tabPanelItems: [{
                title: 'Info',
                text: 'This is Info Tab',
                badge: 'New'
            }, {
                title: 'Contacts',
                text: 'This is Contacts Tab',
                disabled: true
            }, {
                title: 'Address',
                text: 'This is Address Tab',
                icon: 'home'
            }]
        };
    }
};
</script>
React
App.js
import React from 'react';
import 'devextreme/dist/css/dx.light.css';

import TabPanel from 'devextreme-react/tab-panel';

const tabPanelItems = [{
    title: 'Info',
    text: 'This is Info Tab',
    badge: 'New'
}, {
    title: 'Contacts',
    text: 'This is Contacts Tab',
    disabled: true
}, {
    title: 'Address',
    text: 'This is Address Tab',
    icon: 'home'
}];

class App extends React.Component {
    render() {
        return (
            <TabPanel
                items={tabPanelItems}
            />
        );
    }
}

export default App;

If you need a more flexible solution, define itemTemplate and itemTitleTemplate for views and tabs, respectively.

jQuery
JavaScript
HTML
var dataItems = [{
    title: "Info",
    data: { firstName: "John", lastName: "Smith", birthYear: 1986 }
}, {
    title: "Contacts",
    data: { phone: "(555)555-5555", email: "John.Smith@example.com" }
}];

$(function() {
    $("#tabPanelContainer").dxTabPanel({
        items: dataItems,
        itemTitleTemplate: function(itemData, itemIndex, itemElement) {
            itemElement.append("<p>" + itemData.title + "</p>");
        },
        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);
        }
    });
});

jQuery

You can also customize individual items. Declare them as scripts and reference them in the template property or assign a customization function straight to this property.

JavaScript
HTML
$(function() {
    $("#tabPanelContainer").dxTabPanel({
        items: [{
            title: "Info",
            template: function() {
                return $("<p>").text("This is Info Tab");
            }
        }, {
            title: "Contacts",
            template: $("#individualTemplate")
        }]
    });
});
<div id="tabPanelContainer"></div>
<script id="individualTemplate" type="text/html">
    <p>This is Contacts Tab</p>
