DevExtreme Angular - Overview
The TagBox widget is an editor that allows an end user to select multiple items from a drop-down list.
The following code adds the TagBox to your page. The simplest configuration of the widget requires only a dataSource to be specified. In addition, you can specify the placeholder to be displayed when the TagBox is empty.
HTML
TypeScript
- <dx-tag-box
- [dataSource]="products"
- placeholder="Select products...">
- </dx-tag-box>
- import { DxTagBoxModule } from "devextreme-angular";
- // ...
- export class AppComponent {
- products = [
- "HD Video Player",
- "SuperHD Video Player",
- "SuperPlasma 50",
- // ...
- ];
- }
- @NgModule({
- imports: [
- // ...
- DxTagBoxModule
- ],
- // ...
- })
If your data is an array of objects, specify:
- valueExpr
The data field whose value will be written into the value option. - displayExpr
The data field whose value will be displayed in the drop-down list and in the input field of the widget.
