css - Bootstrap - 如何不通过点击打开子菜单

谁能帮帮我？

.dropdown:hover .dropdown-menu
{
  display: block;
}

<nav class="navbar navbar-default">
  <div class="container-fluid">
    <!-- Collect the nav links, forms, and other content for toggling -->
    <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
      <ul class="nav navbar-nav">
        <li class="dropdown">
          <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false">Dropdown <span class="caret"></span></a>
          <ul class="dropdown-menu">
            <li><a href="#">Action</a></li>
            <li><a href="#">Another action</a></li>
            <li><a href="#">Something else here</a></li>
            <li role="separator" class="divider"></li>
            <li><a href="#">Separated link</a></li>
            <li role="separator" class="divider"></li>
            <li><a href="#">One more separated link</a></li>
          </ul>
        </li>
      </ul>
    </div><!-- /.navbar-collapse -->
  </div><!-- /.container-fluid -->
</nav>

菜单由这段代码生成:

<?php
wp_nav_menu( array(
    'menu'              => 'menuPrincipal',
    'theme_location'    => 'primary',
    'depth'             => 2,
    'container'         => 'div',
    'container_class'   => 'collapse navbar-collapse',
    'container_id'      => 'bs-example-navbar-collapse-1',
    'menu_class'        => 'nav navbar-nav navbar-right',
    'fallback_cb'       => 'wp_bootstrap_navwalker::fallback',
    'walker'            => new wp_bootstrap_navwalker())
);

?>

谢谢

代替这个:

.dropdown:hover .dropdown-menu
{
  display: block;
}

试试这个:

li.dropdown:hover > .dropdown-menu {
    display: block;
}

尖括号确保悬停指向正确的(第一个)子元素。
