菜单导航会自动关闭

Question

这是我的导航菜单代码

<button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarResponsive" aria-controls="navbarResponsive" aria-expanded="false" aria-label="Toggle navigation">
          Menu
          <i class="fa fa-bars"></i>
        </button>
        <div class="collapse navbar-collapse" id="navbarResponsive">
          <ul class="navbar-nav ml-auto">
            <li class="nav-item">
              <a class="nav-link" href="http://4343/wordpress/index.php/blogs/">MUSIC</a>
            </li>
           <li class="nav-item">
              <a class="nav-link" href="http://1343.64.5/wordpress/index.php/submit/">SUBMIT</a>
            </li>
          <li class="nav-item">
              <a class="nav-link" href="http://192.16834364.5/wordpress/index.php/contact/">CONTACT</a>
            </li>
          </ul>
        </div>

当我在移动设备上查看我的网站并尝试单击菜单时，它正在关闭。它打开（显示带有项目的下拉菜单）一秒钟，然后关闭。我不知道为什么会这样，有人可以在这里帮助我吗？
