            <GroupSettings Flow="Horizontal"></GroupSettings> 
        </telerik:RadMenuItem> 
    </Items> 
</telerik:RadMenu> 

<script type="text/javascript"> 
function openMenu() 
{ 
    var menu = $find("<%= RadMenu1.ClientID %>"); 
    var item = menu.findItemByText("PRODUCTS"); 
    item.open();     
} 
function redirect()
