Come da titolo ho un template trovato online al quale ho messo i cdn invece che prendere i css e i js dalle varie cartelle :


codice:
            <ul class="list-unstyled topnav-menu float-end mb-0">
               <li class="dropdown d-none d-lg-inline-block">
                  <a class="nav-link dropdown-toggle arrow-none waves-effect waves-light" data-toggle="fullscreen" href="#">
                     <i class="mdi mdi-fullscreen mxn-fs"></i>
                  </a>
               </li>
               <li class="dropdown notification-list topbar-dropdown">
                  <a class="nav-link dropdown-toggle nav-user me-0 waves-effect waves-light" data-bs-toggle="dropdown" href="#" role="button" aria-haspopup="true" aria-expanded="false">
                     <img src="/assets/assets_admin/images/users/admin.jpeg" alt="user-image" class="rounded-circle">
                     <span class="pro-user-name ms-1 text-dark mxn-ls-0">
                        <?= auth()->user()->cognome . ' ' . auth()->user()->nome  ?> <i class="mdi mdi-chevron-down"></i>
                     </span>
                  </a>
                  <div class="dropdown-menu dropdown-menu-end profile-dropdown ">
                     <div class="dropdown-header noti-title">
                        <h6 class="text-overflow m-0">Opzioni Utente</h6>
                     </div>


                     <a href="/user/changePassword" class="dropdown-item notify-item">
                        <i class="mdi mdi-cog-outline"></i>
                        <span>Cambia Password</span>
                     </a>
                     <a href="/user/changeEmail" class="dropdown-item notify-item">
                        <i class="mdi mdi-cog-outline"></i>
                        <span>Cambia Mail</span>
                     </a>
                     <div class="dropdown-divider"></div>
                     <a href="/logout" class="dropdown-item notify-item">
                        <i class="mdi mdi-logout-variant"></i>
                        <span>Logout</span>
                     </a>
                  </div>
               </li>
            </ul>
Il problema è che non scende il dropdown e non ho errori in console , cosa può essere ?
