title: How to achieve submenus
body: <p>I am coding the following in Bootstrap 3.0 and MVC 5. I am trying to get Submenus to work. I referenced <a href="http://getbootstrap.com/components/#navbar" rel="nofollow">navbar documentation</a> but I can't get the Billing and Payment structure to be a sub dropdown menu with this structure:</p>
  
  <pre><code>Account Info
      License Details
      Billing and Payment
         Invoices
         Payments
         Billing
      Users
         User Settings
  </code></pre>
  
  <p>Here is my HTML. I need to replace the anchor tag on Billing Payment. What do I put in its place?</p>
  
  <pre><code>&lt;div class="navbar-collapse collapse"&gt;
                  &lt;ul class="nav navbar-nav"&gt;
                      &lt;li&gt;@Html.ActionLink("Home", "Index", "Home")&lt;/li&gt;
                      &lt;li&gt;@Html.ActionLink("About", "About", "Home")&lt;/li&gt;
                      &lt;li&gt;@Html.ActionLink("Free Trial Setup", "Trial", "Home")&lt;/li&gt;
                      &lt;li class="dropdown"&gt;
                          &lt;a href="#" class="dropdown-toggle" data-toggle="dropdown"&gt;Account Info&lt;/a&gt;
                          &lt;ul class="dropdown-menu"&gt;
                              &lt;li&gt;@Html.ActionLink("License Details", "License", "Home" )&lt;/li&gt;
                              &lt;li class="dropdown-submenu"&gt;&lt;/li&gt;
                                  &lt;a href="#"&gt;Billing and Payment&lt;/a&gt;
                                  &lt;li&gt;@Html.ActionLink("Invoices", "Invoices", "Home")&lt;/li&gt;
                                  &lt;li&gt;@Html.ActionLink("Payments", "Payments", "Home")&lt;/li&gt;
                                  &lt;li&gt;@Html.ActionLink("Billing Information", "Billing", "Home")&lt;/li&gt;
                              &lt;/ul&gt;
                              &lt;li&gt;User Settings&lt;/li&gt;
                          &lt;/ul&gt;
  
                      &lt;/li&gt;
                  &lt;/ul&gt;
                  @Html.Partial("_LoginPartial")
              &lt;/div&gt;
          &lt;/div&gt;
