Create a Group
In the context of the Form UI component, a group is called "group item". A group item can contain simple items, other groups, tabs or empty items. To create a group item, assign "group" to the itemType property. Items nested in the group are configured in the items array. To add a caption to the group, specify the caption property.
jQuery
$(function() { $("#formContainer").dxForm({ formData: { firstName: "John", lastName: "Heart", position: "CEO", phone: "+1(213) 555-9392", email: "jheart@dx-email.com" }, items: [{ itemType: "group", caption: "Personal Data", items: ["firstName", "lastName", "position"] }, { itemType: "group", caption: "Contacts", items: ["phone", "email"] }] }); });
Angular
<dx-form [(formData)]="employee"> <dxi-item itemType="group" caption="Personal Data"> <dxi-item dataField="firstName"></dxi-item> <dxi-item dataField="lastName"></dxi-item> <dxi-item dataField="position"></dxi-item> </dxi-item> <dxi-item itemType="group" caption="Contacts"> <dxi-item dataField="phone"></dxi-item> <dxi-item dataField="email"></dxi-item> </dxi-item> </dx-form>
import { DxFormModule } from "devextreme-angular"; // ... export class AppComponent { employee = { firstName: "John", lastName: "Heart", position: "CEO", phone: "+1(213) 555-9392", email: "jheart@dx-email.com" } } @NgModule({ imports: [ // ... DxFormModule ], // ... })
Vue
<template> <DxForm :form-data="employee"> <DxGroupItem caption="Personal Data"> <DxSimpleItem data-field="firstName" /> <DxSimpleItem data-field="lastName" /> <DxSimpleItem data-field="position" /> </DxGroupItem> <DxGroupItem caption="Contacts"> <DxSimpleItem data-field="phone" /> <DxSimpleItem data-field="email" /> </DxGroupItem> </DxForm> </template> <script> import 'devextreme/dist/css/dx.light.css'; import { DxForm, DxGroupItem, DxSimpleItem } from 'devextreme-vue/form'; const employee = { firstName: 'John', lastName: 'Heart', position: 'CEO', phone: '+1(213) 555-9392', email: 'jheart@dx-email.com' }; export default { components: { DxForm, DxGroupItem, DxSimpleItem }, data() { return { employee }; }, }; </script>
React
import React from 'react'; import 'devextreme/dist/css/dx.light.css'; import { Form, GroupItem, SimpleItem } from 'devextreme-react/form'; const employee = { firstName: 'John', lastName: 'Heart', position: 'CEO', phone: '+1(213) 555-9392', email: 'jheart@dx-email.com' }; class App extends React.Component { render() { return ( <Form formData={employee}> <GroupItem caption="Personal Data"> <SimpleItem dataField="firstName" /> <SimpleItem dataField="lastName" /> <SimpleItem dataField="position" /> </GroupItem> <GroupItem caption="Contacts"> <SimpleItem dataField="phone" /> <SimpleItem dataField="email" /> </GroupItem> </Form> ); } } export default App;
Columns within a Group
Items within a group can be organized in several columns. To specify the number of columns, use the colCount property. 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 group must span.
jQuery
$(function() { $("#formContainer").dxForm({ formData: { firstName: "John", lastName: "Heart", position: "CEO", phone: "+1(213) 555-9392", email: "jheart@dx-email.com" }, // Splits the Form layout in two columns colCount: 2, items: [{ itemType: "group", caption: "Personal Data", // Makes this group span both general columns colSpan: 2, // Organizes items inside this group in three columns colCount: 3, items: ["firstName", "lastName", "position"] }, { itemType: "group", caption: "Contacts", items: ["phone", "email"] }] }); });
Angular
<dx-form [(formData)]="employee" [colCount]="2"> <!-- Splits the Form layout in two columns --> <dxi-item itemType="group" caption="Personal Data" [colSpan]="2" <!-- Makes this group span both general columns --> [colCount]="3"> <!-- Organizes items inside this group in three columns --> <dxi-item dataField="firstName"></dxi-item> <dxi-item dataField="lastName"></dxi-item> <dxi-item dataField="position"></dxi-item> </dxi-item> <dxi-item itemType="group" caption="Contacts"> <dxi-item dataField="phone"></dxi-item> <dxi-item dataField="email"></dxi-item> </dxi-item> </dx-form>
import { DxFormModule } from "devextreme-angular"; // ... export class AppComponent { employee = { firstName: "John", lastName: "Heart", position: "CEO", phone: "+1(213) 555-9392", email: "jheart@dx-email.com" } } @NgModule({ imports: [ // ... DxFormModule ], // ... })
Vue
<template> <DxForm :form-data="employee" :col-count="2"> <DxGroupItem caption="Personal Data" :col-span="2" :col-count="3"> <DxSimpleItem data-field="firstName" /> <DxSimpleItem data-field="lastName" /> <DxSimpleItem data-field="position" /> </DxGroupItem> <DxGroupItem caption="Contacts"> <DxSimpleItem data-field="phone" /> <DxSimpleItem data-field="email" /> </DxGroupItem> </DxForm> </template> <script> import 'devextreme/dist/css/dx.light.css'; import { DxForm, DxGroupItem, DxSimpleItem } from 'devextreme-vue/form'; const employee = { firstName: 'John', lastName: 'Heart', position: 'CEO', phone: '+1(213) 555-9392', email: 'jheart@dx-email.com' }; export default { components: { DxForm, DxGroupItem, DxSimpleItem }, data() { return { employee }; }, }; </script>
React
import React from 'react'; import 'devextreme/dist/css/dx.light.css'; import { Form, GroupItem, SimpleItem } from 'devextreme-react/form'; const employee = { firstName: 'John', lastName: 'Heart', position: 'CEO', phone: '+1(213) 555-9392', email: 'jheart@dx-email.com' }; class App extends React.Component { render() { return ( <Form formData={employee} colCount={2}> <GroupItem caption="Personal Data" colSpan={2} colCount={3}> <SimpleItem dataField="firstName" /> <SimpleItem dataField="lastName" /> <SimpleItem dataField="position" /> </GroupItem> <GroupItem caption="Contacts"> <SimpleItem dataField="phone" /> <SimpleItem dataField="email" /> </GroupItem> </Form> ); } } export default App;
Custom Content within a Group
The Form UI component allows you to place custom content, for example, an image, under the group caption.
jQuery
$("#formContainer").dxForm({ formData: { firstName: "John", lastName: "Heart", picture: "http://here/goes/the/picture.jpg" }, colCount: 2, items: [{ itemType: "group", caption: "Picture", template: function (data, itemElement) { $("<img>").attr("src", data.formData.picture) .appendTo(itemElement) } }, { itemType: "group", caption: "Personal Data", items: ["firstName", "lastName"] }] });
Angular
<dx-form [(formData)]="employee"> <dxi-item itemType="group" caption="Picture" [template]="'pictureTemplate'"> </dxi-item> <dxi-item itemType="group" caption="Personal Data"> <dxi-item dataField="firstName"></dxi-item> <dxi-item dataField="lastName"></dxi-item> </dxi-item> <div *dxTemplate="let data of 'pictureTemplate'"> <img src="{{data.formData.picture}}"> </div> </dx-form>
import { DxFormModule } from "devextreme-angular"; // ... export class AppComponent { employee = { firstName: "John", lastName: "Heart", picture: "http://here/goes/the/picture.jpg" } } @NgModule({ imports: [ // ... DxFormModule ], // ... })
Vue
<template> <DxForm :form-data="employee"> <template #pictureTemplate="{ data }"> <img :src="data.formData.picture"/> </template> <DxGroupItem caption="Picture" template="pictureTemplate" /> <DxGroupItem caption="Personal Data"> <DxSimpleItem data-field="firstName" /> <DxSimpleItem data-field="lastName" /> </DxGroupItem> </DxForm> </template> <script> import 'devextreme/dist/css/dx.light.css'; import { DxForm, DxGroupItem, DxSimpleItem } from 'devextreme-vue/form'; const employee = { firstName: 'John', lastName: 'Heart', picture: 'http://here/goes/the/picture.jpg' }; export default { components: { DxForm, DxGroupItem, DxSimpleItem }, data() { return { employee }; } }; </script>
React
import React from 'react'; import 'devextreme/dist/css/dx.light.css'; import { Form, GroupItem, SimpleItem } from 'devextreme-react/form'; const employee = { firstName: 'John', lastName: 'Heart', picture: 'http://here/goes/the/picture.jpg' }; class App extends React.Component { render() { return ( <Form formData={employee}> <GroupItem caption="Picture" render={pictureRender} /> <GroupItem caption="Personal Data"> <SimpleItem dataField="firstName" /> <SimpleItem dataField="lastName" /> </GroupItem> </Form> ); } } function pictureRender(data) { return ( <img src={data.formData.picture}/> ); } export default App;
