JavaScript/jQuery Gantt - toolbar.items
The Gantt UI component allows you to add default and create custom toolbar items.
jQuery
$(function () { $("#gantt").dxGantt({ //... toolbar: { items: [ 'undo', 'redo', 'separator', { widget: "dxButton", options: { text: "About", icon: "info", stylingMode: "text", onClick: function () { // ... } } } ] } }); });
Angular
<dx-gantt> <dxo-toolbar> <dxi-item name="undo"></dxi-item> <dxi-item name="redo"></dxi-item> <dxi-item name="separator"></dxi-item> <dxi-item widget="dxButton" [options]="customButtonOptions"> </dxi-item> </dxo-toolbar> <dxi-column dataField="title" caption="Subject" [width]="300"></dxi-column> <dxi-column dataField="start" caption="Start Date"></dxi-column> <dxi-column dataField="end" caption="End Date"></dxi-column> </dx-gantt>

html
The Gantt component evaluates the html property's value. This evaluation, however, makes the Gantt potentially vulnerable to XSS attacks. To guard against these attacks, encode the HTML markup before you assign it to the html property. Refer to the following help topic for more information: Potentially Vulnerable API - html.
You can use the text property as a safe alternative.
location
Whatever template you use for UI component items (default or a custom) will be located according to the value specified for the location field in the item data source object.

menuItemTemplate
The following types of the specified value are available.
- Assign a string containing the name of the required template.
- Assign a jQuery object of the template's container.
- Assign a DOM Node of the template's container.
- Assign a function that returns the jQuery object or a DOM Node of the template's container.

name
options
options should contain the properties of the DevExtreme UI component specified in the widget property. Because of this dependency, options cannot be typed and are not implemented as nested configuration components in Angular, Vue, and React. In these frameworks, specify options with an object. We recommend that you declare the object outside the configuration component in Vue and React to prevent possible issues caused by unnecessary re-rendering.
Angular
<dx-toolbar ... > <dxi-item widget="dxCheckBox" [options]="{ text: 'Show IDs' }"> </dxi-item> </dx-toolbar>
import { BrowserModule } from '@angular/platform-browser'; import { NgModule } from '@angular/core'; import { AppComponent } from './app.component'; import { DxToolbarModule } from 'devextreme-angular'; @NgModule({ declarations: [ AppComponent ], imports: [ BrowserModule, DxToolbarModule ], providers: [ ], bootstrap: [AppComponent] }) export class AppModule { }
Vue
<template> <DxToolbar ... > <DxItem ... widget="dxCheckBox" :options="checkBoxOptions" /> </DxToolbar> </template> <script> import 'devextreme/dist/css/dx.light.css'; import DxToolbar, { DxItem } from 'devextreme-vue/toolbar'; export default { components: { DxToolbar, DxItem }, data() { return { checkBoxOptions: { text: 'Show IDs' } } } } </script>
React
import React from 'react'; import 'devextreme/dist/css/dx.light.css'; import Toolbar, { Item } from 'devextreme-react/toolbar'; class App extends React.Component { checkBoxOptions = { text: 'Show IDs' }; render() { return ( <Toolbar ... > <Item widget="dxCheckBox" options={this.checkBoxOptions} /> </Toolbar> ); } } export default App;

template
The following types of the specified value are available.
- Assign a string containing the name of the required template.
- Assign a jQuery object of the template's container.
- Assign a DOM Node of the template's container.
- Assign a function that returns the jQuery object or a DOM Node of the template's container.
The following example adds a custom item to the component. Note that Angular and Vue use custom templates instead of the template property. In React, specify the render property.
jQuery
$(function() { $("#ganttContainer").dxGantt({ // ... items: [ { // ... template: '<div>Custom Item</div>' } ] }); });
Angular
<dx-gantt ... > <dxi-item ... > <div *dxTemplate> <div>Custom Item</div> </div> </dxi-item> </dx-gantt>
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 { DxGanttModule } from 'devextreme-angular'; @NgModule({ declarations: [ AppComponent ], imports: [ BrowserModule, DxGanttModule ], providers: [ ], bootstrap: [AppComponent] }) export class AppModule { }
Vue
<template> <DxGantt ... > <dxItem ... > <div>Custom Item</div> </dxItem> </DxGantt> </template> <script> import DxGantt, { DxItem } from 'devextreme-vue/gantt'; export default { components: { DxGantt, DxItem }, // ... } </script>
React
import React from 'react'; import Gantt, { Item } from 'devextreme-react/gantt'; const renderCustomItem = () => { return <div>Custom Item</div>; } class App extends React.Component { render() { return ( <Gantt ... > <Item ... render={renderCustomItem} > </Item> </Gantt> ); } } export default App;
