导航悬停链接问题

Question

当我将鼠标悬停在每个 li 标签链接上时，它会打开子子菜单，当我将鼠标悬停在链接 3 上时，我无法解决我想要的这个问题，例如它的子菜单只能在它前面打开，当你将鼠标悬停在链接 1 或 2 不显示，我尝试使用不透明度 0 和 1 解决它，但它也不起作用。

HTML

<li class=" dropdown">
    <a class="nav-link" href="#">
       <span>mega-menu</span><i class="fas fa-long-arrow-down ic-sm"></i> </a>
      <ul class="dropdown-content">
          <li><a href="#">Link 1</a></li>
          <li><a href="#">Link 2</a></li>
          <li><a href="#">Link 3 </a>
              <ul class="dropleft-content">
                  <li><a href="">SUB SUB 1</a></li>
                  <li><a href="">SUB SUB 2</a></li>
                  <li><a href="">SUB SUB 2</a></li>
              </ul>
            </li>
      </ul>
