当前我的鼠标指针如果有红色框外它仍然在执行悬停功能，但我需要的是我只需要悬停在红色框中，它开箱即用它会隐藏菜单。

这是我来自 JSfiddle http://jsfiddle.net/KECN7/的来源

这是我的html源代码

     <ul id="menu">
        <li>
            <a href="#" class="btn-function"></a>
            <ul>
                <li><a href="' . wp_logout_url(home_url()) . '">Logout</a></li>
                <li><a href="#">Account Settings</a></li>
                <li><a href="#">Terms & Policies</a></li>           
            </ul>
        </li>
    </ul>

问题是您将红色框应用于元素，但对（更大的）父元素a采取行动。li

您可以将选择器更改为（小提琴）：

#menu li a:hover + ul, #menu li a + ul:hover{
    display: block;
    z-index: 99;    
}

这不是一个完美的解决方案，因为 和 之间的死区a虽然ul，最好的选择是让 .a占用整个空间li。
