    template: `<ejs-multiselect id='multiselectelement' [dataSource]='sportsData' [fields]='fields' [allowCustomValue]='true' [placeholder]='placeholder'></ejs-multiselect>`
})
export class AppComponent {
    constructor() {
    }
    // defined the array of data
    public sportsData: { [key: string]: Object }[] = [
    { id: 'game1', sports: 'Badminton' },
    { id: 'game2', sports: 'Football' },
    { id: 'game3', sports: 'Tennis' }
    ];
    // map the appropriate column
    public fields: Object = { text: 'sports', value: 'id' };
    // set the placeholder to the MultiSelect input
    public placeholder: string = 'Select games';
}
