悬停菜单消失得太快

问题描述

我遇到了问题，我不知道悬浮菜单有什么问题，但是消失太快了

const fixedArr = [...fixed];

/* the code above*/

fixedArr.map(asset => {
    //the code you see above
    }
);

css：

<div class="dropdown">
                        <li class="nav-item log-main">
                            <a href="#" class="nav-link" data-toggle="dropdown">Member</a>
                            <ul class=" dropdown-menu log">
                                <li><a href="sign_in.html" class="dropdown-item">Sign up</a></li>
                                <li><a href="log_in.html" class="dropdown-item">Log in</a></li>
                            </ul>
                        </li>
                    </div>

解决方法

您需要将鼠标悬停在可见的元素和隐藏的下拉菜单中。

.dropdown:hover .dropdown-menu,.dropdown .dropdown-menu:hover{
  display: block;
  position: absolute;
}

<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css" rel="stylesheet"/>
<nav class="navbar navbar-expand-lg navbar-light bg-light">
  <a class="navbar-brand" href="#">Navbar</a>

  <ul class="navbar-nav">

    <li class="nav-item dropdown">
      <a class="nav-link dropdown-toggle" href="#" id="navbarDropdownMenuLink" role="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
          Dropdown link
        </a>
      <div class="dropdown-menu" aria-labelledby="navbarDropdownMenuLink">
        <a class="dropdown-item" href="#">Action</a>
        <a class="dropdown-item" href="#">Another action</a>
        <a class="dropdown-item" href="#">Something else here</a>
      </div>
    </li>
  </ul>

</nav>

您需要在:hover上使用.log-main:hover伪类来显示下一个ul的{{1}}

实时演示：

.dropdown-menu

.navbar .nav-item ul.log {
  display: none;
  list-style-type: none;
}

.log-main:hover .dropdown-menu {
  display: block;
  margin-top: 0;
}

.log a {
  color: var(--main-text-color);
  font-family: var(--main-text-font);
  font-size: 24px;
}
