title: Choosing multiple values in ng-bootstrap Typeahead
body: <p>I am using typeahead from Angular ng-bootstrap - <a href="https://ng-bootstrap.github.io/#/components/typeahead/examples" rel="nofollow noreferrer">https://ng-bootstrap.github.io/#/components/typeahead/examples</a></p>
  <p>Everything is working fine, but I want multiple values on one single text box.</p>
  <p>As that field is a form group, once one value is selected, it should can allow next one, without removing previous one.</p>
