html - CSS 下拉菜单 - 超时

Question

我有一个已转换的下拉菜单，您可以在下面的我的网站上看到，菜单是提交自拍。
我想要做的是，当您将鼠标悬停在 submit a selfie 上时，它会保持打开状态 10 秒。
我已经尝试了各种代码元素来让它工作，但是一旦你的鼠标从出现的菜单上移开它就会关闭。

有什么线索吗？

谢谢

样式表:

<style> 
#layer1 {position:absolute; top:75px; right: 75px}
#layer2 {position:absolute; top:75px; left: 60px}
#layer3 {position:absolute; top:75px; left: 55px}
</style>
<STYLE>body,input{font-family:Calibri,Arial}.text-label{color:#cdcdcd;font-weight:normal}</STYLE>
<style>
/*Initialize*/
ul#menu, ul#menu ul.sub-menu {
    padding:0;
    margin: 0;
}
ul#menu li, ul#menu ul.sub-menu li {
    list-style-type: none;
    display: inline-block;
}
/*Link Appearance*/
ul#menu li a, ul#menu li ul.sub-menu li a {
    text-decoration: none;
    color: #black;
    background: #FFFFFF;
    padding: 5px;
    display:inline-block;
}
/*Make the parent of sub-menu relative*/
ul#menu li {
    position: relative;
}
/*sub menu*/
ul#menu li ul.sub-menu {
    display:none;
    position: absolute;
    top: 40px;
    left: 0;
    width: 200px;
        text-decoration: none;
    color: #black;
    background: #FFFFFF;
    padding: 5px;
    border: 1px solid #CECECE;
}
ul#menu li:hover ul.sub-menu {
    display:block;
}
.fileUpload {
    position: relative;
    overflow: hidden;
    margin: 10px;
}
.fileUpload input.upload {
    position: absolute;
    top: 0;
    right: 0;
    margin: 0;
    padding: 0;
    font-size: 20px;
    cursor: pointer;
    opacity: 0;
    filter: alpha(opacity=0);
}
</style>

这是我的 html 代码，它作为下拉菜单运行:

<div id="layer1"> <ul id="menu">
    <li><IMG align="right" SRC="submit_selfie.jpg">

        <ul class="sub-menu">
            <li>

               <div class="error_box"></div> <?php // http://verifyjs.com ?>
