如何将滚动条添加到下拉菜单?

我正在尝试创建一个下拉菜单,当内容不适合屏幕时,我可以在其中滚动。但是,这不起作用,因为当文本不在屏幕上时,没有滚动条。

我应该怎么做?

这是我的代码:

body {
  overflow-y: hidden;
}

.dropbtn {
  height: 28px;
  width: 50px;
  padding: 16px;
  font-size: 16px;
  border: none;
}

.Panel {
  position: relative;
  display: inline-block;
}

.dropdown-content {
  display: none;
  position: absolute;
  background-color: #f1f1f1;
  min-width: 300px;
  box-shadow: 0px 8px 16px 0px rgba(0, 0, 0, 0.2);
  z-index: 1;
}

.dropdown-content a {
  color: black;
  padding: 12px 16px;
  text-decoration: none;
  display: block;
}

.dropdown-content a:hover {
  background-color: #ddd;
}

.Panel:hover .dropdown-content {
  display: block;
  overflow: auto;
}

.Panel:hover .dropbtn {
  background-size: 28px 50px;
  background-repeat: no-repeat;
  height: 50px;
  width: 28px;
  margin-left: 30px;
}
<body>
  <div class="Panel">
    <button class="dropbtn"></button>
    <div id="myDropdown" class="dropdown-content">
      <br> <br>
      <a href="../" target="_self"> Home</a> <be>
      <a href="../" target="_self"> Other</a> <br>
      <a href="../" target="_self"> Other</a> <br>
      <a href="../" target="_self"> Other</a> <br>
      <a href="../" target="_self"> Other</a> <br>
    </div>
  </div>
</body>

谢谢大家。我找到了解决方案。基本上,我需要给出下拉列表的大小。否则,CSS不会让我滚动。
