I'm using bootstrap to make a dropdown menu for login form, but when I click the image for login I cannot get the dropdown menu to display.

<ul class="nav navbar-right navbar-nav">
  <li>
    <a class="dropdown-toggle" data-toggle="dropdown" data-target=".dropdown-menu" href="#">
      <img src="~/Content/img/user-icon.png" />
    </a>
    <div class="dropdown-menu" style="padding:50px;">
      <form class="form" id="formLogin">
        <input name="username" id="username" type="text" placeholder="Username">enter code here
        <input name="password" id="password" type="password" placeholder="Password">
        <br>
        <button type="button" id="btnLogin" class="btn">Login</button>
        <br>
        <br>
        <p>Don't have an account ? <a><span style="color: blue;">Sign Up</span></a>
        </p>

      </form>
    </div>
  </li>
  <li class="divider-vertical"></li>
  <li>
    <a href="#about" class="cart">
      <img src="~/Content/img/shopping-cart-icon.png" />
      <p id="count-item-in-sc">88</p>
    </a>
  </li>
</ul>

You are missing the jQuery reference. Bootstrap requires jQuery to runt its plugins. I have added the jQuery reference in your fiddle and the menu works ok. Try it.

Check out Bootstrap Documentation.

The parent element needs to be of class dropdown:

<script src="//code.jquery./jquery.min.js"></script>
<link href="//netdna.bootstrapcdn./twitter-bootstrap/2.3.2/css/bootstrap-bined.min.css" rel="stylesheet" type="text/css" />
<script src="//netdna.bootstrapcdn./twitter-bootstrap/2.3.2/js/bootstrap.min.js"></script>

<ul class="nav navbar-right navbar-nav dropdown">
  <li>
    <a class="dropdown-toggle" data-toggle="dropdown" data-target="#" href="#">
      Foobar
    </a>
    <div class="dropdown-menu" style="padding:50px;">
      <form class="form" id="formLogin">
        <p>BAZ form</p>
      </form>
    </div>
  </li>
</ul>

you should add jquery file also. bootstrap is build on jquery.add jquery to your file then it will work. here is working fiddle for you.

<script src="https://ajax.googleapis./ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<head><!-- Latest piled and minified CSS -->
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn./bootstrap/3.3.0/css/bootstrap.min.css">

<!-- Optional theme -->
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn./bootstrap/3.3.0/css/bootstrap-theme.min.css">

<!-- Latest piled and minified JavaScript -->
<script src="https://maxcdn.bootstrapcdn./bootstrap/3.3.0/js/bootstrap.min.js"></script>
  </head>
<body>
  <div class="navbar navbar-default navbar-fixed-top" role="navigation">
