li和lu的可点击下拉菜单

Question

我正在做一个菜单，其中子菜单选项随悬停显示。但这并不好，因为我无法点击第一个下面的其他选项。

所以，我正在尝试创建一个可点击下拉菜单，w3schools有一个页面用div解释这个，但是我用<ul>和<li>做这个，当我点击<li>元素，我把onclick没有任何反应。

那么，用<ul>和<li>做不可能吗？如果有，怎么样？

<script type="text/javascript">
function myFunction() {
    document.getElementById("primero").classList.toggle("show");
}

// Close the dropdown menu if the user clicks outside of it
window.onclick = function(event) {
  if (!event.target.matches('.dropbtn')) {

    var dropdowns = document.getElementsByClassName("dropdown-content");
    var i;
    for (i = 0; i < dropdowns.length; i++) {
      var openDropdown = dropdowns[i];
      if (openDropdown.classList.contains('show')) {
        openDropdown.classList.remove('show');
      }
    }
  }
} 

  </script>
