            </div>
        </li>
    </ul>
</div>

JS

$('.dropdown-menu').on("click.bs.dropdown", function (e) { e.stopPropagation(); e.preventDefault(); });

Is there possible solution ?

The simplest way is to wrap it inside a form since the form will prevent the Dropdown from closing on click...

<nav>
    ...
    <li class="nav-item dropdown">
             <form>
                 <a class="nav-link dropdown-toggle" href="#" id="navbarDropdownMenuLink" data-toggle="dropdown">
                      Dropdown link
                 </a>
                 <div class="dropdown-menu">
                     ....
                 </div>
            </form>
    </li>
    ...
</nav>

The other method is using jQuery to like this:

$('.dropdown-menu .nav-tabs .nav-link').on("click.bs.dropdown", function (e) { 
    $(this).tab('show'); 
    e.stopPropagation(); 
});
