I Have HTML Dropdown Menu like :

<div class="btn-group" role="group">
    <button id="btnGroupDrop1" type="button" class="btn btn-info dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
        SETTINGS
    </button>
    <div class="dropdown-menu" aria-labelledby="btnGroupDrop1">
        <a class="dropdown-item" href="reset">Reset Password</a>
        <a class="dropdown-item" href="logout">Log Out</a>
    </div>
</div>

and the dropdown never showed
