设置引导程序下拉菜单的起点
你好，我的bootstrap下拉菜单有一个问题，每个下拉菜单都必须从第一个nav选项开始，如下图所示。如果您需要更多信息，请告诉我，我会将其添加到这篇文章中。
我已经进行了一些研究，并且看到了一些有关大型菜单的示例，但是我无法在我的项目中使用它，所以我开始自己动手做。

一种快速的，有点棘手的修复程序，但这是我想到使用引导程序的唯一方法。
由于第一个框下拉列表可以正常工作，所以这很好。但是，对于其他三个盒子，我分别给了它们一个类（我使用了dd-2，dd-3和dd-4）。
我所做的只是将position: absolute; left:数字设置为减去按钮的宽度（220像素）
（添加）CSS：
.dd-2 //dropdown box 2 {
left: -220px;
}
.dd-3 //dropdown box 3 {
left: -440px;
}
.dd-4 //dropdown box 4 {
left: -660px;
}
这是我的代码笔，显示了它的用法（很抱歉，我将代码拆分为代码笔）：https://codepen.io/CodeBoyCode/pen/Pyyvgw
让我知道这是否是您想要的
谢谢
