               <a class="nav-link" href="#clanek03">Olimpija</a>
            </li>
            <li class="nav-item">
               <a class="nav-link" href="#dodaj-clanek">Dodaj nov članek</a>
            </li>
         </ul>

So I'm having trouble implementing the Botstrapp hamburger menu. The problem is that it just doesn't crash ... I included the required link and script tags, but it still doesn't work. I also deleted all the body content and copied and pasted the entire navigation bar straight from the Bottstrap site, but it still doesn't work.

bootstrap-5 html

Your code is good but I think you imported your scripts or styles for Bootstrap 5 incorrectly.

You can try to run the below snippet with full integration with your navigation bar.

<!DOCTYPE html>
<html lang="en">

It would work if you include the bootstrap javascript.
