Twitter bootstrap 如何在禁用下拉切换的情况下使用引导下拉悬停？

我正在我的网站上使用引导。我正在尝试添加一个链接到下拉列表，它在桌面浏览器上运行良好。但不在移动设备上工作。我怎样才能修好它们？ 这是我的密码：

<nav id="navbar-primary" class="navbar navbar-default" role="navigation">
    <div class="navbar-header">
      <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#navbar-primary-collapse">
        <span class="sr-only">Mobile</span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
        <span class="icon-bar"></span>
      </button>
    </div>
    <div class="collapse navbar-collapse" id="navbar-primary-collapse">
      <ul class="nav navbar-nav">
        <li class="dropdown">
          <a href="dropdownlink.html" class="dropdown-toggle disabled" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false">DROPDOWN<span class="caret"></span></a>
          <ul class="dropdown-menu">
            <li><a href="link1.html">LINK 1</a></li>
            <li><a href="link2.html">LINK 2</a></li>
          </ul>
        </li>
</ul>
</div>
</nav>

所以，当我单击手机上的下拉列表时，浏览器将转到dropdownlink.html，并且菜单未打开。我该怎么修理

@media screen and (min-width: 768px) {
    ul.nav li.dropdown:hover > ul.dropdown-menu {
    display: block;
  }
}

@media screen and (max-width: 768px) {
ul.nav li.dropdown.open > ul.dropdown-menu {
    display: block;
  }
ul.nav li.dropdown > ul.dropdown-menu {
    display: none;
  }
 }

@media screen and (min-width: 768px) {
    ul.nav li.dropdown:hover > ul.dropdown-menu {
    display: block;
  }
}

@media screen and (max-width: 768px) {
ul.nav li.dropdown.open > ul.dropdown-menu {
    display: block;
  }
ul.nav li.dropdown > ul.dropdown-menu {
    display: none;
  }
 }
