options

Configures the DevExtreme UI component used as a toolbar item.

Type:

Object

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

app.module.ts
<dx-toolbar ... >
    <dxi-item
        widget="dxCheckBox"
        [options]="{ text: 'Show IDs' }">

</dx-toolbar>
import { BrowserModule } from '@angular/platform-browser';

        );
    })
