CSS和IE 8问题与下拉菜单

Question

下拉菜单未在顶级菜单按钮下对齐。任何线索如何解决这个问题？ （我收到一条错误消息，告诉我必须添加更多文本，所以这里有）。当您翻转顶级菜单选项时，下方会显示一个下拉菜单。但是，在IE 8中，选项不会下拉到菜单项下，而是刷新到页面的左侧。这是网站：http://www.aerlawgroup.com。

HTML：

<div id="nav-wrap">
        <div class="container">
            {menu}
            <div style="clear:both"></div>
        </div>
    </div>

CSS：

#nav-wrap .container{/*controls spacing above menu */
    clear: both;
    overflow: hidden;
    position: relative;
    padding: 14px 0px 0px 0px;
}
#nav-wrap {
    clear: both;
    padding:0;
    margin:0;

    overflow:hidden !important;
}

    #nav-wrap .container ul li:last-child,
