登录使用html下拉菜单

登录后，我想创建一个下拉菜单，为我的帐户和订单等添加一个位置。

我的页面混乱（登录时）：

这是我的代码，但是除了弄乱我的网站外，它实际上什么也没做。（请注意，某些php是我试图在欢迎页面上显示用户名的方法。）

<?php
        if (isset($_SESSION['userId'])) {
            require './includes/dbh.inc.php';
            /*$sql = mysqli_query($conn,"SELECT fnidUser, lnidUsers FROM users"); */
            $result = mysqli_query($conn, "SELECT fnidUser FROM users");

            echo "


            <li class='login current2'><a href='#'>Welcome</a>
                <ul>
                    <li class='login'><a href='#'>My Account</a></la>
                    <li class='login'><a href='#'>My Orders</a></la>
                    <li class='login'><a href='#'>My Wishlist</a></la>
                    <li class='login'><a href='#'>My Cart</a></la>
                    <li class='login'><a action='./includes/logout.inc.php' method='post' name='logout-submit'>Log out</a></la>
                </ul>
            </li>


            ";

    }
        else{
            echo "<li class='login current2'><a href='login.php'>Login / Sign up</a></li>";
                    }
?>

这是我对该页面的所有样式。
