                <span class="sr-only">Toggle navigation</span>
                <span class="icon-bar"></span>

                <span class="icon-bar"></span>
            </button>
            <a class="navbar-brand" href="/">Get Started</a>
        </div>
        <!-- Collect the nav links, forms, and other content for toggling -->
        <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
            <ul class="nav navbar-nav navbar-right">
    <li>
            <form class="navbar-form navbar-left" role="search" action="/search/" method="GET" id="search" autocomplete="off">
    <div class="form-group">
      <input type="text" class="form-control" placeholder="Select what to search for" name="query" width="100px">
      <select name="drop" class="form-control" width="20">
      <option value="1"> Assigns</option>
      <option value="2"> Subjects(Tutorials)</option>
      <option value="3"> Subjects(Papers)</option>
      </select>
    </div>
    <button type="submit" class="btn btn-default"><span class="glyphicon glyphicon-search"></span></button>
  </form>


    </li>
                <li>
                    <a href="#home">Home</a>
                </li>
                <li>
                    <a href="#about">About</a>
                </li>
                <li>
                    <a href="#contact">Contact us</a>
                </li>
            </ul>
        </div>

        <!-- /.navbar-collapse -->
    </div>
    <!-- /.container -->
</nav>

解决方案

Your toggle target doesn't match your collapse ID:

<button type="button"... data-target="#navigationbar">

<div class="collapse navbar-collapse" id="navigationbar">
