CSS菜单帮助（第二个菜单消息）(CSS Menu Help (Second menu dissapear))

我想把这个css菜单放在一起，但我无法正常工作。 当您浏览顶部菜单中的任何链接时，它会打开第二个菜单，但是当您继续它时，第二个菜单会消失。 另外，它错位了。 我不能把它放在左边：0

#menu {width:800px;background-color:#FFF;min-height:30px;border:0;border-top:2px solid #8BD2E4;padding:0 5px;margin:0 auto;}
#nmenu {list-style:none;padding:0;margin:0;width:700px;}
#nmenu li {display:inline;float:left;height:20px;margin-left:45px;position:relative;}
#nmenu li.frst {margin-left:0}
#nmenu li a {font: 11px/30px Tahoma, Geneva, sans-serif;text-decoration:none;color:#979598;letter-spacing:2px;font-weight:bold;text-transform:uppercase;}
#smedia {width:100px;height:30px;float:left;}
#fb, #tw, #pt {background: #FFF url(smedia.png) no-repeat center;width:16px;height:16px;display:block;float:right;margin:7px 3px;}
#fb {background-position: -1px -1px;}
#tw {background-position: -18px -1px;}
#pt {background-position: -35px -1px;}
#nmenu li ul {display:none;position:absolute;top:30px;left:0;border:1px solid red;background-color:#FFF;}
#nmenu li:hover ul {display:block}
#nmenu li ul li {float:left;width:100px;}
I am trying to put this css menu together but I couldn`t get it working right. When you go over any link in top menu it opens up second menu although second menu disappears when you go on it. Plus, its misplaced. I couldn't place it in left:0

 试试下面的css： 
 
#nmenu li {
    display: inline;
    float: left;
    margin-left: 44px;
    position: relative;
}

#nmenu li ul {
    background-color: #FFFFFF;
    border: 1px solid red;
    display: none;
    left: -5px;
    padding: 0;
    position: absolute;
    top: 30px;
}

#nmenu li a {
    color: #979598;
    display: block;
    font: bold 11px/30px Tahoma,Geneva,sans-serif;
    letter-spacing: 2px;
    padding-left: 2px;
    text-decoration: none;
    text-transform: uppercase;
}
try the below css:
 
#nmenu li {
    display: inline;
    float: left;
    margin-left: 44px;
    position: relative;
}

#nmenu li ul {
    background-color: #FFFFFF;
    border: 1px solid red;
    display: none;
    left: -5px;
    padding: 0;
    position: absolute;
    top: 30px;
}

#nmenu li a {
    color: #979598;
    display: block;
    font: bold 11px/30px Tahoma,Geneva,sans-serif;
    letter-spacing: 2px;
    padding-left: 2px;
    text-decoration: none;
    text-transform: uppercase;
}
