html - 更改下拉位置

Question

我制作了一个导航菜单，但我希望它的下拉菜单固定如下:

http://jsfiddle.net/Pnn6V/380/

在该示例中，无论鼠标悬停在哪个菜单上，下拉菜单始终固定在同一位置。

我希望导航菜单上的下拉菜单位置相同。

这是我的代码:

@inherits Umbraco.Web.Macros.PartialViewMacroPage
@{

    var rootNode = Model.Content.AncestorOrSelf(1);

    // home node is hardcoded - this might not be right?
    <ul id="menu">
        <li>
            <a href="/" class="drop">Home</a>
            <div class="dropdown_2columns">
                <!-- Begin 2 columns container -->
                <div class="col_2">
                    <h2>Welcome !</h2>
                </div>
            </div><!-- End 2 columns container -->
        </li><!-- End Home Item -->
        @foreach (var mainNode in rootNode.Children())
        {
            int childCount = 1;
            int numChildren = mainNode.Children().Count();
            <li>
                <a href="@mainNode.Url" class="drop">@mainNode.Name</a>
                <div class="dropdown_5columns">
                    <!-- Begin 2 columns container -->
                    <div class="col_5">
                        <h2>@mainNode.Name</h2>
                    </div>
                    @* note if you want ALL descendants change .Children to .Descendats*@
                    @foreach (var childNode in mainNode.Children())
                    {
                        // if first node or new set of three open the div and ul @: is used to stop razor trying to
                        // "balance" the tags
                        if (childCount == 1 || (double)childCount % 3 == 1)
                        {
                            @:<div class="col_1">
                                @:<ul>
                        }
                        <a href="@childNode.Url">@childNode.Name</a>

                        // close the div and list if this is either a multiple of 3 or the last one
                        if ((double)childCount % 3 == 0 || numChildren == childCount)
                        {
                            @:</ul>
                        @:</div>
                        }
                        childCount++;
                    }
                </div>
            </li>
        }
    </ul>
}

我的导航现在看起来像这样

如何使下拉菜单固定在导航菜单的正下方，如我上面显示的示例？

Answer 1

#menu li:hover .dropdown_1column
{
    left:-841px;
    top:auto;
}
#menu li:hover .dropdown_2columns
{
    left:-841px;
    top:auto;
} 
#menu li:hover .dropdown_3columns
{
    left:-841px;
    top:auto;
}
#menu li:hover .dropdown_4columns
{
    left:-248px;
    top:auto;
}  
#menu li:hover .dropdown_5columns {  
    left:-841px;  
    top:auto;  
}  

使左边的属性相等
