title: Bootstrap 5 with Angular 12 : bootstrap (navbar, dropdown) interactions are blocked after get/create bootstrap instances by JavaScript
body: <p>Everything (navbar, dropdown) works fine until I try to get/create bootstrap instances in the .ts files. When I insert the get/create instance js code I can't collapse the nav-menu after I expanded and the dropdown is not working either!</p>
  <p>Here is the source code on <a href="https://stackblitz.com/edit/angular-ivy-ah3inn" rel="nofollow noreferrer">stackblitz</a></p>
  <p>If you are commenting out the following code part, everything works fine!</p>
  <pre><code> var modal = new Modal('#updatePwaModal');
   modal.show();
  </code></pre>
