Yes ...at the end of the day ... 

the next step is adding fallowing code in to the layout.master after art-nav...

                    }
                </script>
                <%--- ----%>

somehow there is problem about links... i think i must check the code that appending menu content in Menu1_DataBound ...

after then changing the  navigate url in foreach makes the job for me..

....

menuText.AppendLine("<h3><a href='" + "/"+System.IO.Path.GetFileName(lvl2.NavigateUrl) + "'>" +
                                        lvl2.Text + "</a></h3>");

                                    //create ul list if any children
                                    if (lvl2.ChildItems.Count > 0)
                                    {
                                        menuText.AppendLine("<ul>");
                                        foreach (MenuItem lvl3 in lvl2.ChildItems)
                                        {
                                            menuText.AppendLine("<li><a href='" + "/"+System.IO.Path.GetFileName(lvl3.NavigateUrl) + "'>" +
                                                lvl3.Text + "</a></li>");
                                        }
                                        menuText.AppendLine("</ul>");
                                    }

...
