title: Chips in angular with bootstrap with no material dependency
body: <p><strong>Details</strong>:
  Angular v9
  Bootstrap 4
  @ng-bootstrap/ng-bootstrap v5.2.1</p>
  
  <p>I tried <a href="https://www.npmjs.com/package/ngx-chips" rel="nofollow noreferrer">ngx-chips</a>, but it is dependent on angular material. And my project is using bootstrap.
  For now I am using <a href="https://ng-select.github.io/ng-select#/tags" rel="nofollow noreferrer">ng-select</a> with tags.
  Can anyone suggest some other option?</p>
