我是Bootstrap的新用户，对我的导航栏有疑问。 这是我的测试站点。 TEST-DOMAIN
我目前正在将Bootstrap 4.3.1与JQuery 3.4.1结合使用。
菜单的外观和功能在桌面上都很棒。下拉出现按预期方式。我在下拉菜单中添加了列，以进行各种超级菜单。
当网站过渡到移动网站时，下拉菜单显示在父菜单项的“右侧”。有没有办法使它显示在父项的下方，并将菜单的其余部分向下推到其下方？
我尝试将下拉列表设置为Display：absolute，这在其他关于此的文章中找到。但是，尽管将下拉菜单如我所愿地向左移动，但它却将其浮动在菜单其余部分的上方。我希望它向左对齐，同时将菜单的其余部分推到下面。
感谢您的帮助！

我已经删除了所有用于NavBar的自定义CSS，以确保我所做的编辑没有做错任何事情。
