Html 如何解决下拉菜单的定位问题

这是我现在的html和css代码

<div class="header">
<div class="container-fluid">
  <div class="row">
    <div class="col-1"></div>
    <div class="col-10"></div>
    <div class="col-1 dropdown">
      <button class="btn" type="button" id="dropdownMenuButton" data-toggle="dropdown" aria-haspopup="true"
        aria-expanded="false">
        Menu
        <i class="fa fa-bars"></i>
      </button>
      <div class="dropdown-menu">
        <a class="dropdown-item" href="#">About </a>
        <a class="dropdown-item" href="#">Education</a>
        <a class="dropdown-item" href="#">Hobbies</a>
        <a class="dropdown-item" href="#">Contact</a>
      </div>
    </div>
  </div>
</div>

我想让下拉菜单移到右边而不是左边

---

但是我的代码是这样的，如果你使用引导，你不需要任何定制的css

默认情况下，下拉菜单自动定位在距父菜单顶部100%的位置，并沿父菜单的左侧。将.dropdown menu右键添加到.dropdown menu右键对齐下拉菜单

参考：

演示：

菜单

.header{
position: relative;
top: 20px;
}

.dropdown-menu {
min-width: 120px !important;
height: 145px !important;
position: relative;
right: 0;
}

body {
background-color: lightblue;
} 

<div class="header">
  <div class="container-fluid">
    <div class="row">
      <div class="col-1"></div>
      <div class="col-10"></div>
      <div class="col-1 dropdown">
        <button class="btn" type="button" id="dropdownMenuButton" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
          Menu
          <i class="fa fa-bars"></i>
        </button>
        <div class="dropdown-menu dropdown-menu-right">
          <a class="dropdown-item" href="#">About </a>
          <a class="dropdown-item" href="#">Education</a>
          <a class="dropdown-item" href="#">Hobbies</a>
          <a class="dropdown-item" href="#">Contact</a>
        </div>
      </div>
    </div>
  </div>
