      <nav class="navbar navbar-expand-sm bg-dark navbar-dark">
        <a class="navbar-brand" href="#">Logo!</a>
        <ul class="navbar-nav position-static">
          <li class="nav-item">
            <a class="nav-link" href="#">Link 1</a>
          </li>
          <li class="nav-item dropdown">
            <a class="nav-link dropdown-toggle" href="#" id="navbardrop" data-toggle="dropdown">
              Dropdown 1
            </a>
            <div class="dropdown-menu w-100">
              <a class="dropdown-item" href="#">Link 1</a>
              <a class="dropdown-item" href="#">Link 2</a>
              <a class="dropdown-item" href="#">Link 3</a>
            </div>
          </li>
          <li class="nav-item dropdown">
            <a class="nav-link dropdown-toggle" href="#" id="navbardrop" data-toggle="dropdown">
              Dropdown 2
            </a>
            <div class="dropdown-menu w-100 left-taken">
              <a class="dropdown-item" href="#">Link 1</a>
              <a class="dropdown-item" href="#">Link 2</a>
              <a class="dropdown-item" href="#">Link 3</a>
            </div>
          </li>
        </ul>
      </nav>

CSS:

.left-taken {
