Question

我有一个带有垂直子菜单的水平菜单，但我想让下拉子菜单也是水平的。我一直试图在没有运气的情况下完成这项工作。这是一个例子http://jsfiddle.net/bukYf/这是我菜单的CSS ..

/* Navigation Menu Styles */
#nav {
    margin: 0;
    padding: 7px 6px 0;

    line-height: 100%;
}
#nav li {
    margin: 0 5px;
    padding: 0 0 8px;
    float: left;
    position: relative;
    list-style: none;
}


/* main level link */
#nav a {
    font-weight: bold;
    color: #65a7ed;
    text-decoration: underline;
    display: block;
    padding:  8px 10px;
    margin: 0;

    -webkit-border-radius: 1.6em;
    -moz-border-radius: 1.6em;

}
#nav a:hover {
    background: #fff;
    color: #000;
}

/* main level link hover */
#nav .current a, #nav li:hover > a {
    background: #65a7ed url(img/gradient.png) repeat-x 0 -40px;
    color: #fff;
    border-top: solid 1px #f8f8f8;

    -webkit-box-shadow: 0 1px 1px rgba(0,0,0, .2);
    -moz-box-shadow: 0 1px 1px rgba(0,0,0, .2);
    box-shadow: 0 1px 1px rgba(0,0,0, .2);


}

/* sub levels link hover */
#nav ul li:hover a, #nav li:hover li a {
    background: none;
    border: none;
    color: #666;

    -webkit-box-shadow: none;
    -moz-box-shadow: none;
}
#nav ul a:hover {
    background: #0078ff url(img/gradient.png) repeat-x 0 -100px !important;
    color: #fff !important;

    -webkit-border-radius: 0;
    -moz-border-radius: 0;

    text-shadow: 0 1px 1px rgba(0,0,0, .1);
}

/* dropdown */
#nav li:hover > ul {
    display: block;
}

/* level 2 list */
#nav ul {
    display: none;

    margin: 0;
    padding: 0;
    width: 70px;
    position: absolute;
    top: 35px;
    left: 0;
    background: #b6d1ee url(img/gradient.png) repeat-x 0 0;
    border: solid 1px #b4b4b4;

    -webkit-border-radius: 10px;
    -moz-border-radius: 10px;
    border-radius: 10px;

    -webkit-box-shadow: 0 1px 3px rgba(0,0,0, .3);
    -moz-box-shadow: 0 1px 3px rgba(0,0,0, .3);
    box-shadow: 0 1px 3px rgba(0,0,0, .3);
}
#nav ul li {
    float: none;
    margin: 0;
    padding: 0;
    text-align:center;
}

#nav ul a {
    font-weight: normal;
}

/* level 3+ list */
#nav ul ul {
    left: 61px;
    top: -3px;
}

/* rounded corners of first and last link */
#nav ul li:first-child > a {
    -webkit-border-top-left-radius: 9px;
    -moz-border-radius-topleft: 9px;

    -webkit-border-top-right-radius: 9px;
    -moz-border-radius-topright: 9px;
}
#nav ul li:last-child > a {
    -webkit-border-bottom-left-radius: 9px;
    -moz-border-radius-bottomleft: 9px;

    -webkit-border-bottom-right-radius: 9px;
    -moz-border-radius-bottomright: 9px;
}

/* clearfix */
#nav:after {
    content: ".";
    display: block;
    clear: both;
    visibility: hidden;
    line-height: 0;
    height: 0;
}
#nav {
    display: inline-block;
} 
html[xmlns] #nav {
    display: block;
}

* html #nav {
    height: 1%;
}

我确信答案很简单我只是无法完成它。
