Angular Toolbar - items
The items array can contain:
- Strings
- Objects with fields described in this section
- Objects with any other fields. In this case, specify the itemTemplate.
If you need to update the UI component items, reassign the entire items array as shown in the following example:
toolbarInstance.option('items', newItems);
As an alternative to items, you can use the dataSource property. It accepts the DataSource object, whose underlying stores provide an API that allows you to update individual items without reassigning the entire item collection.
html
The Toolbar component evaluates the html property's value. This evaluation, however, makes the Toolbar 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.

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.

jQuery
$(function() { $("#toolbar").dxToolbar({ items: [{ // ... menuItemTemplate (data, index) { return $(`<div><i class='dx-icon-favorites'></i>${data.options.text}</div>`); } }], }); });
Angular
<dx-toolbar> <dxi-item ... menuItemTemplate="menu-item" > </dxi-item> <div *dxTemplate="let data of 'menu-item'"> <i class="dx-icon-favorites"></i> {{data.options.text}} </div> </dx-toolbar>
Vue
<template> <DxToolbar> <dxItem ... menu-item-template="menu-item" > </dxItem> <template #menu-item="{ data }"> <i class="dx-icon-favorites"></i> {{data.options.text}} </template> </DxToolbar> </template> <script> // ... </script>
React
import React from 'react'; import Toolbar, { Item } from 'devextreme-react/toolbar'; const renderMenuItem = (data) => { return <div><i class="dx-icon-favorites"></i> {data.options.text}</div>; } function App() { return ( <Toolbar> <Item ... menuItemRender={renderMenuItem} > </Item> </Toolbar> ); } export default App;

options
jQuery
$('#toolbar').dxToolbar({ items: [{ // ... widget: 'dxCheckBox', options: { text: 'Show IDs' }, }] });
Angular
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. Specify options with an object.
<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
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. Specify options with an object. We recommend that you declare the object outside the configuration component to prevent possible issues caused by unnecessary re-rendering.
<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
