jquery - css水平下拉定位

Question

大家好，我正在尝试制作一个水平下拉菜单，我已经制作了一个关于我的问题的 JS Fiddle 以及一张我想要它的样子的图片。

我的问题是我无法让子菜单位于我想要的位置(在容器的右侧)当我将我的子 UL 设置为绝对定位时，它不会比它的父级更宽，并且被迫垂直。我从来没有做过水平下拉，只有垂直。

    <div id="head">
    <div class="container">
        <a href="#"><strong class="logo pull-left"><h1>CAVO</h1>
        </strong></a> <!-- end logo !-->
        <ul class="nav pull-right">
            <li><a href="#">Menu</a>
                <ul>
                    <li><a href="#">Starters</a></li>
                    <li><a href="#">Breakfast and Brunch</a></li>
                    <li><a href="#">Salads</a></li>
                    <li><a href="#">Sandwiches and Wraps</a></li>
                    <li><a href="#">Pasta</a></li>
                    <li><a href="#">Mains</a></li>
                    <li><a href="#">Pizza</a></li>
                </ul>
            </li>
            <li><a href="#">About Us</a></li>
            <li><a href="#">Contact</a></li>
        </ul>
    </div><!-- end container !-->
</div> <!-- end header !-->

在您现有的 CSS 中，添加以下内容:

ul ul{
    position:relative;
    right:-194px;
}
ul li:first-child{
    text-align:right;
}

这是一个 demo .
