感谢您的提前帮助!我希望孩子出现在右边,而父母不要动,但我不知道我错过了定位属性。

我正在尝试构建一个垂直的全屏覆盖菜单(从徽标图像触发),其中父项具有子菜单项,但是我希望它们显示在“父母栏”的右侧。问题在于,当子元素悬停显示时,下一个父元素会向下移动...

答案 0 :(得分:1)

您应该将属性position: absolute添加到“子菜单”:

.encima ul {
  position: absolute;
}

答案 1 :(得分:0)

您在HTML结构中犯了错误,请使用ul内的子菜单li并从

更改一个CSS。
.encima li ul {
    display: none;
    width: 100%;
}

  document.getElementById("myNav").style.height = "100%";
