无法将菜单放入Bootstrap 3中的容器中

以下是显示垂直菜单栏的代码，当我运行代码dropdown时，菜单从引导程序container中退出。

有人可以帮忙吗，如何将div放在容器中？

菜单应仅放置在container内部，但在我的情况下，<div class="container">不会展开。

.mega-dropdown {
  border: 2px solid #e0e0e0;

.mega-dropdown.active:before {
  content: "";
  position: absolute;

  right: -2px;

因此，如果我做对了，您希望首先显示顶级菜单项，然后单击其中的任何一个，您要在被单击项的正下方显示子菜单。

如果是这种情况，则可以使用“数据切换”和“如下所示的数据taregt属性”来达到此效果。

<nav>
    <ul class="nav">        
        <li><a href="#" id="btn1" data-toggle="collapse" data-target="#submenu" aria-expanded="false">Toggle Me</a>
            <ul class="nav collapse" id="submenu" role="menu" aria-labelledby="btn1">
                <li><a href="#">Submenu1</a></li>
                <li><a href="#">Submenu2</a></li>
                <li><a href="#">Submenu3</a></li>
            </ul>
        </li>   
    </ul>
</nav>

这只是一个示例，使用此逻辑进一步构建其他菜单项，它们将在单击的项的正下方打开。
