Question

我正在为网站的导航栏工作，但我特别在子菜单上遇到问题。我注意到只显示了一个子菜单，但其余的都是“隐藏”的。

例如，子菜单仅显示“Resources For”，而不显示在“Resources and Support”下的其他选项卡，例如“Basic Rights”，“Health”，“For Educators”。子菜单甚至不会出现在其他选项卡上，例如“程序”主标签下的“奖学金”。我似乎无法理解为什么子菜单没有出现。如果有人可以提供帮助，那将非常感激。

这是live example：

这是HTML：

 public class CustomMultiSelectorCallback extends ModalMultiSelectorCallback {

        private int count;
        public CustomMultiSelectorCallback(MultiSelector multiSelector) {
            super(multiSelector);
        }

        @Override
        public boolean onCreateActionMode(ActionMode actionMode, Menu menu) {
            super.onCreateActionMode(actionMode, menu);
            count = 0;
            actionMode.getMenuInflater().inflate(R.menu.list_item_delete, menu);
            return true;
        }

这是CSS：

        <!-- Sticky Navigation -->
<div class="nav-wrapper">
            <ul>
                <li>
                    <a href="#">ABOUT US</a>

Answer 1

这是因为它们都是不正确的包装（只是以不同的方式）

<li><a href="./resources/index.html">RESOURCES FOR</a> <!-- no closing li like the others-->
  <ul class ="submenu">
      <li></li>
 </ul>
 <!-- which means that the submenu^^ is still inside it -->
<li><a href="rights.html">BASIC RIGHTS</a></li> <!-- closing li -->
  <ul class ="submenu">
      <li></li>
  </ul>
  <!-- this submenu^^ is not in the li, which means that none of the CSS applies since it is not 'li ul.submenu'. It is only 'ul.submenu' -->

要修复，请将ul.submenu标记包裹在li中。

<li><a href="rights.html">BASIC RIGHTS</a>
  <ul class ="submenu">
      <li></li>
  </ul>
</li><!-- closing li down here-->

为什么我的子菜单没有显示？
