        <div class="dropdown-menu">
            <a class="dropdown-item"> @Html.ActionLink("Account Type", "Index", "AccountTypeTables", null, null) </a>
            <a class="dropdown-item" href="signup.html">Register</a>
        </div>
    </li>

Answer 1

You need to make sure your page contains the css and js:

<ul class="nav nav-tabs">
<li class="nav-item dropdown">
        <a class="nav-link dropdown-toggle" href="#" role="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
            Finance
        </a>
        <div class="dropdown-menu">
            <a class="dropdown-item"> @Html.ActionLink("Account Type", "Index", "AccountTypeTables", null, null) </a>
            <a class="dropdown-item" href="signup.html">Register</a>
        </div>
</li>
</ul>
