bootstrap 4 navbar öffnet innerhalb div

Question

Ich benutze den Bootstrap 4 navbar in einer eckigen App. Das Problem ist, dass das Menü innerhalb des Divs öffnet - das ist die beste Erklärung, die ich gefunden habe! d. h. erhöht die Größe des div.

<nav class="navbar navbar-toggleable-md navbar-light bg-faded"> 
    <div class="collapse navbar-collapse" id="navbarNavDropdown"> 
    <ul class="navbar-nav"> 
     <li class="nav-item dropdown"> 
      <a class="nav-link dropdown-toggle" id="users" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false"> 
       Usrs 
      </a> 
      <div class="dropdown-menu" aria-labelledby="users"> 
       <a class="dropdown-item" href="#">u1</a> 
       <a class="dropdown-item" href="#">u2</a> 
       <a class="dropdown-item" href="#">u3</a> 
      </div> 
      </li> 
     <li class="nav-item dropdown"> 
     <a class="nav-link dropdown-toggle" id="tickets" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false"> 
      Tickets 
     </a> 
     <div class="dropdown-menu" aria-labelledby="tickets"> 
      <a class="dropdown-item" href="#">t1</a> 
      <a class="dropdown-item" href="#">t2</a> 
      <a class="dropdown-item" href="#">t3</a> 
     </div> 
     </li> 
    </ul> 
    </div> 
</nav> 

Dies ist ein Beispiel dafür, was in meiner app geschieht, und was auf dem Bootstrap-KB happen basiert:
