引导程序下拉菜单四处移动，样式不显示

只编写了几个月的代码，非常感谢您的帮助：）

我设计了一个向左浮动的徽标和向右浮动的行动呼吁（CTA）按钮的客户标题，我想在点击后将其变成下拉菜单。我借用Bootstrap的Dropdown组件。我遇到了一些问题：

1. 如何打开按钮下方的下拉列表：我已转动徽标图标进入下拉菜单，所有链接都显示在Bootstrap已设置为默认颜色。单击徽标时在Google Chrome中，菜单直接显示在图标（即在我想要的地方）。但是当在Mozilla中点击徽标时下拉菜单在图标左侧打开并移动图标结束我试过"向右拉"类，但这并不能让下拉菜单在图标下方但在其右侧。如何创建可以说是一门"拉低"课程，并确保它能在浏览器
2. 如何为同一标题中的另一个按钮复制该下拉菜单：对于CTA按钮，我应用了与左浮动图标的下拉列表，所以理论上，它应该工作方式相同。但是，下拉菜单选项不会显示，除非我将鼠标悬停在选项。看起来它在某个地方继承了一个属性告诉它将字体设为白色并覆盖Bootstrap的属性。问题是，我的课都没有"颜色：white/#ffffff"在任何地方，所以我不确定它是从哪里继承的属性
3. 对于CTA按钮，下拉菜单也会向左打开而不是在底部。当我把代码粘贴到外面时对于任何父div（作为独立的），菜单也会向左打开并将按钮向右移动，而不是朝底部
