Angular TabPanel - Getting Started

NOTE

Before you start the tutorial, ensure DevExtreme is installed in your Angular, Vue, React, or jQuery application.

The TabPanel UI component consists of the Tabs and MultiView components. The TabPanel automatically synchronizes the selected tab with the currently displayed view and vice versa.

This tutorial explains how to add a TabPanel to a page and configure its core features. The following control demonstrates the result:

Refer to the sections below for more information about each configuration step. The full code is available in the following GitHub repository: getting-started-with-tabpanel.

Create the TabPanel

jQuery

Add DevExtreme to your jQuery application and use the following code to create a TabPanel:

index.js

index.html

index.css

$(function() {
    $("#tabPanel").dxTabPanel({
        // Configuration goes here
    });
});

<html>
    <head>
        <!-- ... -->
        <script type="text/javascript" src="https://code.jquery.com/jquery-3.5.1.min.js"></script>

        <link rel="stylesheet" href="https://cdn3.devexpress.com/jslib/20.2.12/css/dx.common.css">
        <link rel="stylesheet" href="https://cdn3.devexpress.com/jslib/20.2.12/css/dx.light.css">
        <link rel="stylesheet" href="index.css">

        <script type="text/javascript" src="https://cdn3.devexpress.com/jslib/20.2.12/js/dx.all.js"></script>
        <script type="text/javascript" src="index.js"></script>
    </head>
    <body class="dx-viewport">
        <div id="tabPanel"></div>
    </body>
</html>

#tabPanel {
    height: 250px;
    width: 500px;
}

Angular

Add DevExtreme to your Angular application and use the following code to create a TabPanel:

app.component.html

app.component.ts

app.module.ts

app.component.css

<dx-tab-panel id="tabPanel">
    <!-- Configuration goes here -->
</dx-tab-panel>

import { Component } from '@angular/core';

@Component({
    selector: 'app-root',
    templateUrl: './app.component.html',
    styleUrls: ['./app.component.css']
})
export class AppComponent {

}

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { AppComponent } from './app.component';

import { DxTabPanelModule } from 'devextreme-angular';

@NgModule({
    declarations: [
        AppComponent
    ],
    imports: [
        BrowserModule,
        DxTabPanelModule
    ],
    providers: [ ],
    bootstrap: [AppComponent]
})
export class AppModule { }

#tabPanel {
    height: 250px;
    width: 500px;
}

Vue

Add DevExtreme to your Vue application and use the following code to create a TabPanel:

App.vue

<template>
    <DxTabPanel id="tabPanel">
        <!-- Configuration goes here -->
    </DxTabPanel>
</template>

<script>
import 'devextreme/dist/css/dx.common.css';
import 'devextreme/dist/css/dx.light.css';

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

export default {
    components: {
        DxTabPanel
    }
}
</script>

<style>
#tabPanel {
    height: 250px;
    width: 500px;
}
</style>

React

Add DevExtreme to your React application and use the following code to create a TabPanel:

App.js

App.css

import React from 'react';
import 'devextreme/dist/css/dx.common.css';
import 'devextreme/dist/css/dx.light.css';

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

const App = () => {
    return (
        <TabPanel id="tabPanel">
            {/* Configuration goes here */}
        </TabPanel>
    );
}

export default App;

#tabPanel {
    height: 250px;
    width: 500px;
}

Create Tabs

Populate the items[] array with data items. The TabPanel generates a tab with a view for each item in this array.

Specify a tab's title and/or icon properties to configure an individual tab. The code below uses icons from the DevExtreme icon library. You can also use the badge property to create a badge with custom text.

jQuery

index.js

$(function(){   
    $("#tabPanel").dxTabPanel({
        items: [{ 
            title: "Employee",
            icon: "floppy",
            // ...
        }, {
            title: "Notes",
            icon: "comment",
            // ...
        }, {
            title: "Role",
            icon: "isnotblank",
            badge: "new",
            // ...
        }]
    });
});

Angular

app.component.html

<dx-tab-panel>
    <dxi-item title="Employee" icon="floppy">
        <!-- ... -->
    </dxi-item>
    <dxi-item title="Notes" icon="comment">
        <!-- ... -->
    </dxi-item>
    <dxi-item title="Role" icon="isnotblank" badge="new">
        <!-- ... -->
    </dxi-item>
</dx-tab-panel>

Vue

App.vue

<template>
    <DxTabPanel>
        <DxItem title="Employee" icon="floppy">
            <!-- ... -->
        </DxItem>
        <DxItem title="Notes" icon="comment">
            <!-- ... -->
        </DxItem>
        <DxItem title="Role" icon="isnotblank" badge="new">
            <!-- ... -->
        </DxItem>
    </DxTabPanel>
</template>

<script>
import 'devextreme/dist/css/dx.common.css';
import 'devextreme/dist/css/dx.light.css';

import DxTabPanel, { DxItem } from "devextreme-vue/tab-panel";

export default {
    components: {
        DxTabPanel,
        DxItem
    }
}
</script>

React

App.js

import React from 'react';
import 'devextreme/dist/css/dx.common.css';
import 'devextreme/dist/css/dx.light.css';

import TabPanel, { Item } from "devextreme-react/tab-panel";

const App = () => {
    return (
        <TabPanel>
            <Item title="Employee" icon="floppy">
                {/* ... */}
            </Item>
            <Item title="Notes" icon="comment">
                {/* ... */}
            </Item>
            <Item title="Role" icon="isnotblank" badge="new">
                {/* ... */}
            </Item>
        </TabPanel>
    );
}

export default App;

The code above produces the following output:

DevExtreme TabPanel: Customized Tabs

You can also use the itemTitleTemplate property to specify a custom template for all tabs. items.tabTemplate overrides the itemTitleTemplate property and allows you to specify a template for an individual tab. This approach is not shown in this tutorial, but you can refer to the property descriptions for details.

Specify View Content

You can use the following properties to specify view content:

itemTemplate
Specifies a custom template for all views.
items[].template
Specifies a custom template for an individual view. This property overrides itemTemplate.
items[].text
Specifies text displayed in an individual view.
noDataText
Specifies text or markup to display when views do not have content.

This tutorial demonstrates the use of the items[].template property. This property allows you to specify different content for individual views. In the code below, the views contain the Form, TextArea, and RadioGroup UI components.

jQuery

index.js

$(function(){   
    $("#tabPanel").dxTabPanel({
        items: [{ 
            title: "Employee",
            icon: "floppy",
            template: function (itemData, itemIndex, element) {
                const formDiv = $("<div style='padding:15px'>")
                formDiv.dxForm({
                    formData: employeeData,
                    items: ["name", "position", "hireDate", "officeNumber"]
                });
                formDiv.appendTo(element);
            }
        }, {
            title: "Notes",
            icon: "comment",
            template: function (itemData, itemIndex, element) {
                const textAreaDiv = $("<div style='padding:15px; height: 100%'>")
                textAreaDiv.dxTextArea({
                    value: employeeData.notes
                });
                textAreaDiv.appendTo(element);
            }
        }, {
            title: "Role",
            icon: "isnotblank",
            badge: "new",
            template: function (itemData, itemIndex, element) {
                const radioGroupDiv = $("<div style='padding:15px'>")
                radioGroupDiv.dxRadioGroup({
                    items: employeeData.roles,
                    value: employeeData.roles[0]
                });
                radioGroupDiv.appendTo(element);
            }
        }]
    });

    const employeeData = {
        name: "John Heart",
        position: "CEO",
        hireDate: new Date(2012, 4, 13),
        officeNumber: 901,
        notes: "John has been in the Audio/Video industry since 1990. He has led DevAV as its CEO since 2003.",
        roles: ["Chief Officer", "Manager", "Administrator"]
    };
});

Navigate Between Tabs

Specify the following properties to configure navigation between tabs:

swipeEnabled
Specifies whether users can switch between views with the swipe gesture.
loop
Specifies whether to loop views.
animationEnabled
Specifies whether to animate the change of the current view.
selectedIndex
Specifies the index of the currently selected tab. Use this property to switch between tabs programmatically. In this tutorial, this property's value depends on the the RadioGroup's selected item (see tabSwitcherRadioGroup).
