【问题描述】：

我正在使用引导导航栏，并且我有一个可折叠的导航栏。但我面临一个奇怪的问题，每当我打开我的网站，即手机或平板电脑（实际上我需要可折叠导航栏的设备）时，会出现按钮但我无法打开导航栏。这不应该发生。如果我点击导航栏按钮（三行按钮）没有任何反应。

            <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#collapsable-nav" aria-expanded="false">
              <span class="sr-only">Toggle navigation</span>
              <span class="icon-bar"></span>
              <span class="icon-bar"></span>
              <span class="icon-bar"></span>
            </button> 
          </div>

          <div id="collapsable-nav" class="collapse navbar-collapse">
            <ul id="nav-list" class="nav navbar-nav navbar-right">
              <li>
                <a href="menu-categories.html">
                  <span class="glyphicon glyphicon-cutlery"></span>
                  <br class="hidden-xs">Menu
                </a>
              </li>
              <li>
                <a href="#">
                  <span class="glyphicon glyphicon-info-sign"></span>
                  <br class="hidden-xs">About
                </a>
              </li>
              <li>
                <a href="#">
                  <span class="glyphicon glyphicon-certificate"></span>
                  <br class="hidden-xs">Awards
                </a>
              </li>
              <li id="phone" class="hidden-xs">
                <a href="tel:410-602-5008">
                  <span>410-602-5008</span>
                </a>
                <div>* We Deliver</div>
              </li>
            </ul>
          </div>
