Vueを使用してドロップダウンメニューを実装するにはどうすればよいですか?

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

.dropdown-content {
  display: none;
  position: absolute;
  top: 100%;
  left: 0;
  background-color: #fff;
  min-width: 160px;
  z-index: 1;
  padding: 10px;
  box-shadow: 0px 8px 16px 0px rgba(0,0,0,0.2);
}

.dropdown:hover .dropdown-content {
  display: block;
}

<div class="dropdown">
  <button>下拉菜单</button>
  <div class="dropdown-content">
    <a href="#">选项1</a>
    <a href="#">选项2</a>
