RadMenu and Yaml

[dnn]

i want to combine DotNetNuke - Yaml - RadMenu
but i have a problem with the radmenu.

i created the base html code with the yaml application (http://builder.yaml.de/) - it creates a css based layout and this html layout i implimented into a dotnetnuke skin and there i put the radmenu control.

but the the menu don't works correct - the sub menus are behind my div layout - you can see it at my attached screen.

here is my code at the acsx skin file:

<div class="page_margins">
    <div class="page">
        <div id="header">
            <dnn:LOGO runat="server" ID="dnnLOGO" />
        </div>
        <div id="nav">
            <dnn:RADMENU runat="server" ID="dnnMENU" SkinsPath="~/DesktopModules/telerik.skinobjects/SkinsRadMenu/" Skin="Office2007" />
        </div>
        <div id="main">
            <div id="col1">
                <div id="col1_content" class="clearfix">
                    <div id="LeftPane" runat="server"></div>
                </div>
            </div>
            <div id="col2">
                <div id="col2_content" class="clearfix">
                    <div id="RightPane" runat="server"></div>
                </div>
            </div>
            <div id="col3">
                <div id="col3_content" class="clearfix">
                    <div id="ContentPane" runat="server"></div>
                </div>
                <!-- IE Column Clearing -->
                <div id="ie_clearing"></div>
            </div>
        </div>
        <div id="footer">
            <div id="FooterPane" runat="server"></div>
            <dnn:USER runat="server" CssClass="Login" ID="dnnUser" />
            &nbsp;|&nbsp;<dnn:LOGIN runat="server" CssClass="Login" ID="dnnLogin" />
        </div>
    </div>
</div>

thanks for help

i found the problem.

for the div id=nav tag was a style overflow: hidden at the css file.

after deleting this style it works fine.
