i'm trying to use demo:

<asp:Menu ID="EntertainmentMenu" runat="server" Orientation="Horizontal" CssSelectorClass="SimpleEntertainmentMenu">
    <Items>
        <asp:MenuItem Text="Music">
            <asp:MenuItem Text="Classical" />
            <asp:MenuItem Text="Rock">
                <asp:MenuItem Text="Electric" />
                <asp:MenuItem Text="Acoustical" />
            </asp:MenuItem>
            <asp:MenuItem Text="Jazz" />
        </asp:MenuItem>
        <asp:MenuItem Text="Movies">
            <asp:MenuItem Text="Action" />
            <asp:MenuItem Text="Drama" />
            <asp:MenuItem Text="Musical" />
        </asp:MenuItem>
        <asp:MenuItem Text="Movies">
            <asp:MenuItem Text="Action" />
            <asp:MenuItem Text="Drama" />
            <asp:MenuItem Text="Musical" />
        </asp:MenuItem>
        <asp:MenuItem Text="Movies">
            <asp:MenuItem Text="Action" />
            <asp:MenuItem Text="Drama" />
            <asp:MenuItem Text="Musical" />
        </asp:MenuItem>
    </Items>
</asp:Menu>

everything is right, but... the menu is shown in 2 rows, why?

the example is this:

http://www.asp.net/CSSAdapters/WalkThru/SimpleMenu.aspx , same css.

to install i do this:

1. Add the appropriate file to your App_Browsers directory.
   2. Add the compiled CSSFriendly.dll to your web site's bin directory.
