Grouping
The suggestion list items can be grouped by providing a header for each set of items. The grouping will be defined based on the groupBy in fields object.
Here the category field is mapped with groupBy field.
<input type="text" ej-autocomplete width="300" [dataSource]="countries" [fields]="fields" [showPopupButton]="true" watermarkText="Search a country" />export class AppComponent {
countries: Array<any>;
fields: Object;
constructor() {
