Could somebody answer for me whether it is possible to have multiple menus (i.e. seperate menu trees)? I'm trying to add both a horizontal menu at the top of my site and a sidebar menu, both of which should be visible on all pages. I've tried looking through the documentation, but from what I can find it's only possible to have one menu-tree. The code I'm currently using in my layout.Master file is:

    <form id="frmMain" runat="server">
    <asp:SiteMapDataSource ID="SiteMapData" runat="server" ShowStartingNode="false" />
    <asp:SiteMapDataSource ID="PageMapDataSource" runat="server" ShowStartingNode="false" />
    <asp:SiteMapDataSource ID="ChildPageSiteMapData" runat="server" ShowStartingNode="false" />

<div id="topmenu">
     <asp:Panel id="divTopMenu" runat="server" visible="True" SkinID="pnlPlain">
     <portal:SiteMenu ID="SiteMenu1" runat="server" UseTreeView="false" HideMenuOnSiteMap="false" Direction="Horizontal" ></portal:SiteMenu>
            <asp:ContentPlaceHolder ID="topContent" runat="server"></asp:ContentPlaceHolder>
        </asp:Panel>
</div>

<div id="leftmenu">
     <asp:Panel id="divLeft" runat="server" cssclass="leftside" visible="True" SkinID="pnlPlain">
     <portal:PageMenu id="PageMenu1" runat="server" UseTreeView="true" Direction="Vertical" DynamicDisplayLevels="0" StartingNodeOffset="0" TreeViewShowExpandCollapse="false" TreeViewExpandDepth="2" />
            <asp:ContentPlaceHolder ID="leftContent" runat="server"></asp:ContentPlaceHolder>
        </asp:Panel>
</div>

Any feedback would be greatly appreciated. Please let me know if I can provide further details
