Question

当用户点击或悬停汉堡包菜单时，我遇到了关于弹出菜单内容的问题。 Angular是我的应用程序的基础，我有一些在视图javascript和css，以使这个工作，但没有得到理想的结果。我的截图显示了这个角落：

问题是您的菜单位于＆＃34;汉堡包菜单上方＃34;。发生这种情况是因为唯一不可点击的元素是那些设置为display: none;或pointer-events: none;的元素。

您可以按照以下方式解决此问题：

#menu_items.menu_items_toggle {
  opacity: 1;
  top: 100%;
  display: inline-block;
}

注意我是如何将id（#menu_items）添加到选择器中，以便在不添加!important的情况下提高CSS选择器的特异性。

要使用menu_items样式，您必须添加display: none;。

#menu_items {
  position: absolute;
  top: 0%;
  opacity: 0;
  transition: all 0.5s;
  display: none;
}

菜单推出时点击或悬停问题
