Question

我的导航菜单出现问题，显示在jquery手风琴小部件下。抱歉，我无法附上图片，但基本上下拉菜单显示在jquery小部件下面。

这是我的导航菜单的CSS，我使用标准的jquery ui手风琴。

.menu,
.menu ul,
.menu li,
.menu a {
    margin: auto;
    padding: 0;
    border: none;
    outline: none;
}
.menu { 
    height: 40px;
    width: 950px;
        margin-bottom: 5px;
    background: #4c4e5a;
    background: -webkit-linear-gradient(top, #4c4e5a 0%,#2c2d33 100%);
    background: -moz-linear-gradient(top, #4c4e5a 0%,#2c2d33 100%);
    background: -o-linear-gradient(top, #4c4e5a 0%,#2c2d33 100%);
    background: -ms-linear-gradient(top, #4c4e5a 0%,#2c2d33 100%);
    background: linear-gradient(top, #4c4e5a 0%,#2c2d33 100%);

    -webkit-border-radius: 5px;
    -moz-border-radius: 5px;
    border-radius: 5px;
}

.menu li {
    position: relative;
    list-style: none;
    float: left;
    display: block;
    height: 40px;
}

.menu li.nolink {
        height: 28px;
    display: block;
    padding: 0 14px;
    margin: 6px 0;
    line-height: 28px;
    text-decoration: none;

    border-left: 1px solid #393942;
    border-right: 1px solid #4f5058;

    font-size: 13px;

    color: #f3f3f3;
    text-shadow: 1px 1px 1px rgba(0,0,0,.6);
