如何在 Blogger 的下拉导航 CSS 中向子菜单添加二级

Question

我真的很纠结我的模板。这是我当前导航菜单的 css。我已经尝试了几件事，但没有给我第二个子菜单，它会在我已经打开的下拉菜单的右侧弹出。谁能帮我插入代码以允许第二次弹出？谢谢！！！

Answer 1

好的，如果你编辑HTML和CSS，你可以这样做：

.HTML

其中一个 HTML 下拉菜单如下所示：

<li><a class='ai' href='#'>Dropmenu</a>
  <ul class='menus'>
    <li><a href='#'>Dropmenu 1</a></li>
    <li><a href='#'>Dropmenu 2</a></li>
    <li><a href='#'>Dropmenu 3</a></li>
    <li><a href='#'>Dropmenu 4</a></li>
    <li><a href='#'>Dropmenu 5</a></li>
  </ul>
</li>

在

下拉菜单</a>标记后添加此代码：

  <ul class='menus'>
    <li><a href='#'>Dropmenu 1</a></li>
    <li><a href='#'>Dropmenu 2</a></li>
    <li><a href='#'>Dropmenu 3</a></li>
    <li><a href='#'>Dropmenu 4</a></li>
    <li><a href='#'>Dropmenu 5</a></li>
  </ul>

所以它看起来像这样：

<li><a class='ai' href='#'>Dropmenu</a>
  <ul class='menus'>
    <li><a href='#'>Dropmenu 1</a>
      <ul class='menus'>
        <li><a href='#'>Dropmenu 1</a></li>
        <li><a href='#'>Dropmenu 2</a></li>
        <li><a href='#'>Dropmenu 3</a></li>
        <li><a href='#'>Dropmenu 4</a></li>
        <li><a href='#'>Dropmenu 5</a></li>
      </ul>
    </li>
    <li><a href='#'>Dropmenu 2</a></li>
    <li><a href='#'>Dropmenu 3</a></li>
    <li><a href='#'>Dropmenu 4</a></li>
    <li><a href='#'>Dropmenu 5</a></li>
  </ul>
</li>

.CSS

然后，添加此 CSS：

#menu .menus li > ul.menus {
  transform: translateX(100%) scale(1.0);
  top: 0;
}
#menu ul.menus {
  overflow: visible !important;
}

最终结果

完成后，它应如下所示：

/* CSS Main Menu */
#menu .menus li > ul.menus {
   transform: translateX(100%) scale(1.0);
   top: 0;
}
#menu ul.menus {
  overflow: visible !important;

注意：而不是：

#menu ul.menus {
  overflow: visible !important;
}

您可以删除#menu ul.menus上的overflow: hidden。
