Question

代码：

<div class="navbar navbar-default navbar-static-top">
    <div class="container">
        <div class="navbar-header">
            <button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse">
                <span class="n-bar"></span>
                <span class="n-bar"></span>
                <span class="n-bar"></span>
            </button>
            <a class="navbar-brand" href="test"><img src="img/logo.png" alt=""/></a>
        </div>
        <div class="navbar-collapse collapse ">
            <ul class="nav navbar-nav">
                <li><a href="#">menu1</a></li>
                <li><a href="#">menu2</a></li>
                <li><a href="#">menu3</a></li>
            </ul>
        </div>
    </div>
</div>

在这段代码中，我创建了一个bootstrap导航菜单，即menu1，menu2＆amp;菜单3。现在，我希望当我将鼠标悬停在任何导航菜单上时，它会在菜单底部显示一个框，例如：https://www.flipkart.com/。那么，我该怎么办呢？请帮帮我。

谢谢

试试这个：

<div class="navbar navbar-default navbar-static-top">
    <div class="container">
        <div class="navbar-header">
            <button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse">
                <span class="n-bar"></span>
                <span class="n-bar"></span>
                <span class="n-bar"></span>
            </button>
            <a class="navbar-brand" href="test"><img src="img/logo.png" alt=""/></a>
        </div>
        <div class="navbar-collapse collapse dropdown">
            <button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-collapse">
            Button
            </button>
            <ul class="nav navbar-nav dropdown-list">
                <li><a href="#">menu1</a></li>
                <li><a href="#">menu2</a></li>
                <li><a href="#">menu3</a></li>
            </ul>
        </div>
    </div>
</div>

CSS：

.dropdown-list {
  position: absolute;
  display:none;
}

.dropdown {

  position: relative;
}

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