Question

当我将鼠标悬停在每个li标签链接上时，它将打开子菜单，当我将鼠标悬停在链接3（例如，其子菜单仅在其前面打开）以及将鼠标悬停在链接3上时，我无法解决此问题链接1或2它什么都不显示，我试图通过使用不透明度0和1来解决它，但是它也不起作用。

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>
