title: BootStrap Navbar-Toggle Not Working In asp.net Using Visual Studio 2010
body: <p>I have installed nuget package then I installed bootstrap. Now I have folders </p>
  
  <pre><code>Contents
   containing bootstrap css files 
  Scripts 
   containing .js files 
  </code></pre>
  
  <p>In header of Master Page I have included it like this </p>
  
  <pre><code>&lt;script type="text/javascript" src="~/Scripts/bootstrap.js"&gt;&lt;/script&gt;
  &lt;script type="text/javascript" src="~/Scripts/bootstrap.min.js"&gt;&lt;/script&gt;
  &lt;script type="text/javascript" src="~/Scripts/jquery-1.9.1.js"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>Then I tried to make nav like </p>
  
  <pre><code>&lt;div class="navbar navbar-default" role="navigation"&gt;
      &lt;div class="navbar-header"&gt;
        &lt;button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse"&gt;
          &lt;span class="sr-only"&gt;Toggle navigation&lt;/span&gt;
          &lt;span class="icon-bar"&gt;&lt;/span&gt;
          &lt;span class="icon-bar"&gt;&lt;/span&gt;
          &lt;span class="icon-bar"&gt;&lt;/span&gt;
        &lt;/button&gt;
        &lt;a class="navbar-brand" href="#"&gt;Project name&lt;/a&gt;
      &lt;/div&gt;
      &lt;div class="navbar-collapse collapse"&gt;
        &lt;ul class="nav navbar-nav"&gt;
          &lt;li class="active"&gt;&lt;a href="#"&gt;Link&lt;/a&gt;&lt;/li&gt;
          &lt;li&gt;&lt;a href="#"&gt;Link&lt;/a&gt;&lt;/li&gt;
          &lt;li&gt;&lt;a href="#"&gt;Link&lt;/a&gt;&lt;/li&gt;
          &lt;li class="dropdown"&gt;
            &lt;a href="#" class="dropdown-toggle" data-toggle="dropdown"&gt;Dropdown &lt;b class="caret"&gt;&lt;/b&gt;&lt;/a&gt;
            &lt;ul class="dropdown-menu"&gt;
              &lt;li&gt;&lt;a href="#"&gt;Action&lt;/a&gt;&lt;/li&gt;
              &lt;li&gt;&lt;a href="#"&gt;Another action&lt;/a&gt;&lt;/li&gt;
              &lt;li&gt;&lt;a href="#"&gt;Something else here&lt;/a&gt;&lt;/li&gt;
              &lt;li class="divider"&gt;&lt;/li&gt;
              &lt;li class="dropdown-header"&gt;Nav header&lt;/li&gt;
              &lt;li&gt;&lt;a href="#"&gt;Separated link&lt;/a&gt;&lt;/li&gt;
              &lt;li&gt;&lt;a href="#"&gt;One more separated link&lt;/a&gt;&lt;/li&gt;
            &lt;/ul&gt;
          &lt;/li&gt;
        &lt;/ul&gt;
        &lt;ul class="nav navbar-nav navbar-right"&gt;
          &lt;li class="active"&gt;&lt;a href="./"&gt;Default&lt;/a&gt;&lt;/li&gt;
          &lt;li&gt;&lt;a href="../navbar-static-top/"&gt;Static top&lt;/a&gt;&lt;/li&gt;
          &lt;li&gt;&lt;a href="../navbar-fixed-top/"&gt;Fixed top&lt;/a&gt;&lt;/li&gt;
        &lt;/ul&gt;
      &lt;/div&gt;&lt;!--/.nav-collapse --&gt;
    &lt;/div&gt;
  </code></pre>
