修复右侧的下拉菜单和导航菜单

Question

我有两个关于下拉菜单的问题

1. 当我打开下拉菜单时，它位于右侧而不是下方。我该如何更改？

子菜单没问题

1. 当我用我的电脑打开时，它没问题，但它在移动模式 (Android) 中出现故障。如何修复我的导航菜单，它是透明的，我想让背景变黑？

你可以在这里看到我的代码：

顺便说一句，你用什么工具来解决 HTML 和 CSS 的问题？我是新手。

编辑：为了满足您的需求，您需要将子菜单和子子菜单拆分为不同的类，以便您可以对它们进行不同的样式设置。请参阅此更改的更新代码。

就使用 Stack Overflow 的工具而言，建议使用您将在下面看到的内置代码片段工具。要纠正您的间距问题，您需要摆脱您设置的 180px 并使用诸如百分比之类的动态内容。在这种情况下，将其设置为宽度的 100% 可以纠正该问题。

请包含更多代码以调查移动问题。

document.addEventListener('click', function(e) {
  e = e || window.event;
  var target = e.target || e.srcElement;
  if (target.parentElement && target.parentElement.className.indexOf('has-submenu') > -1) {
    e.target.parentElement.classList.toggle('open');
  }
}, false);
