Conditional Role based menu display

I have form where I am displaying menu based on the AD group the person belongs to

<div class="navbar-collapse collapse" style="background-color:#04397d; "><ul class="nav navbar-nav" style="font-weight:bold;font-size:1.3em;color:white;" id="smenu" ><li><asp:Image ID="Logo" runat="server" ImageUrl="~/images/LogoText.png" style="padding-right:140px;padding-top:4.2%;" /></li><li><a runat="server" href="~/default.aspx"   >Home</a></li><% if (Roles.IsUserInRole("DMN\\WW_UPL"))
                               { %><li><a runat="server" href="~/secure/Upload/Upload.aspx" >Upload</a></li><%} %><% if (Roles.IsUserInRole("DMN\\WW_ADM"))
                               { %><li><a runat="server" href="~/secure/Upload/Upload.aspx" >Upload</a></li><li><a runat="server" href="~/secure/Admin/Add.aspx" >Administration</a></li><%} %><% if (Roles.IsUserInRole("DMN\\WW_AAM"))
                               { %><li><a runat="server" href="~/secure/Admin/Add.aspx" >Administration</a></li><%} %></ul>

when a user belongs to more than one AD group, the menu items are being repeated.

Is there anyway to use else if statement in the condition?
