Create a Tab
The Form UI component allows you to organize items in tabs. In the context of the Form, tabs are called "tabbed items". A tabbed item can contain simple items, other tabs, groups or empty items. To create a tabbed item, assign "tabbed" to the itemType property. To specify the collection of tabs, use the tabs array. To define items displayed within an individual tab, use its items array.
- import React from 'react';
- import 'devextreme/dist/css/dx.light.css';
- import { Form, SimpleItem, TabbedItem, Tab } from 'devextreme-react/form';
- const employee = {
- name: 'John Heart',
- position: 'CEO',
- hireDate: new Date(2012, 4, 13),
- city: 'Los Angeles',
- phone: '+1(213) 555-9392',
- email: 'jheart@dx-email.com'
- };
- class App extends React.Component {
- render() {
- return (
- <Form formData={employee}>
- <SimpleItem dataField="name" />
- <TabbedItem>
- <Tab title="Info">
- <SimpleItem dataField="position" />
- <SimpleItem dataField="hireDate" />
- <SimpleItem dataField="city" />
- </Tab>
- <Tab title="Contacts">
- <SimpleItem dataField="phone" />
- <SimpleItem dataField="email" />
- </Tab>
- </TabbedItem>
- </Form>
- );
- }
- }
- export default App;
Columns within a Tab
The content of a tab can be organized in columns. The colCount property instructs the tab about how many columns it must have. Note that the entire Form layout can also be organized in columns if the colCount property is declared on the root level. In this case, use the colSpan property to define how many general columns the tab must span.
- import React from 'react';
- import 'devextreme/dist/css/dx.light.css';
- import { Form, SimpleItem, TabbedItem, Tab } from 'devextreme-react/form';
- const employee = {
- name: 'John Heart',
- position: 'CEO',
- hireDate: new Date(2012, 4, 13),
- city: 'Los Angeles',
- phone: '+1(213) 555-9392',
- email: 'jheart@dx-email.com'
- };
- class App extends React.Component {
- render() {
- return (
- <Form
- formData={employee}
- colCount={2}>
- <SimpleItem dataField="name" />
- <TabbedItem colSpan={2}>
- <Tab
- title="Info"
- colCount={3}>
- <SimpleItem dataField="position" />
- <SimpleItem dataField="hireDate" />
- <SimpleItem dataField="city" />
- </Tab>
- <Tab
- title="Contacts"
- colCount={2}>
- <SimpleItem dataField="phone" />
- <SimpleItem dataField="email" />
- </Tab>
- </TabbedItem>
- </Form>
- );
- }
- }
- export default App;
Custom Content within a Tab
The Form UI component allows you to specify custom templates for an individual tab and its content. Assign callback functions to the tabRender and render properties, respectively.
- import React from 'react';
- import 'devextreme/dist/css/dx.light.css';
- import { Form, SimpleItem, TabbedItem, Tab } from 'devextreme-react/form';
- const employee = {
- name: 'John Heart',
- birthDate: new Date(1964, 3, 15),
- position: 'CEO',
- city: 'Los Angeles',
- phone: '+1(213) 555-9392',
- email: 'jheart@dx-email.com'
- };
- class App extends React.Component {
- render() {
- return (
- <Form formData={employee}>
- <SimpleItem dataField="name" />
- <TabbedItem colSpan={2}>
- <Tab
- title="Data Protection Policy"
- tabRender={tabRender}
- render={tabContentRender} />
- <Tab title="Info">
- <SimpleItem dataField="position" />
- <SimpleItem dataField="birthDate" />
- <SimpleItem dataField="city" />
- </Tab>
- <Tab title="Contacts">
- <SimpleItem dataField="phone" />
- <SimpleItem dataField="email" />
- </Tab>
- </TabbedItem>
- </Form>
- );
- }
- }
- function tabRender(data) {
- return (
- <p style={{color:'red'}}>{ data.title }</p>
- );
- }
- function tabContentRender(data) {
- return (
- <p>
- <i>By filling out this form, you agree
- to the terms of the <a href='#'>Data Protection Policy</a></i>
- </p>
- );
- }
- export default App;

Configure the Tab Panel
For displaying tabs, the Form uses the TabPanel UI component. Therefore, you can specify any properties of the TabPanel in the tabPanelOptions object.
- import React from 'react';
- import 'devextreme/dist/css/dx.light.css';
- import { Form, SimpleItem, TabbedItem, Tab, TabPanelOptions } from 'devextreme-react/form';
- const employee = {
- firstName: 'John',
- lastName: 'Heart',
- hireDate: new Date(2012, 4, 13),
- city: 'Los Angeles',
- phone: '+1(213) 555-9392',
- email: 'jheart@dx-email.com'
- };
- class App extends React.Component {
- constructor() {
- super();
- this.tabPanelTitleClick = this.tabPanelTitleClick.bind(this);
- }
- render() {
- return (
- <Form formData={employee}>
- <SimpleItem dataField="firstName" />
- <SimpleItem dataField="lastName" />
- <TabbedItem>
- <TabPanelOptions
- height="250"
- onTitleClick={this.tabPanelTitleClick} />
- <Tab title="Info">
- <SimpleItem dataField="hireDate" />
- <SimpleItem dataField="city" />
- </Tab>
- <Tab title="Contacts">
- <SimpleItem dataField="phone" />
- <SimpleItem dataField="email" />
- </Tab>
- </TabbedItem>
- </Form>
- );
- }
- tabPanelTitleClick(e) {
- // ...
- }
- }
- export default App;
