javascript - Regarding multiple master pages in mvc4 -

i have 1 master page named site.master in have tabs logic

  <div id="menubar">         @html.simplenav(new[] {             new simplenavitem{text="home", action="index", controller = "home",getselected = ((a, c) => (c == "home" && == "index"))},             new simplenavitem{text="blog", action="index", controller = "blog", getselected = ((a, c) => (c == "blog" && == "index"))},             new simplenavitem{text="about", action="about", controller = "home", getselected = ((a, c) => c == "home" && == "about")},             new simplenavitem{text="contact", action="contact", controller = "home", getselected = ((a, c) => c == "home" && == "contact")}         }) %>     </div> 

tab logic class file code

 public static class simplenavextensions {     public static string simplenav(this htmlhelper html, ienumerable<simplenavitem> navitems)     {         var urlhelper = new urlhelper(html.viewcontext.requestcontext);         string controller = html.viewcontext.routedata.values["controller"].tostring();         string action = html.viewcontext.routedata.values["action"].tostring();          tagbuilder ul = new tagbuilder("ul");         ul.addcssclass("clearfix");          stringbuilder listbuilder = new stringbuilder();         tagbuilder li = null;         tagbuilder = null;         foreach (var item in navitems)         {             = new tagbuilder("a");             a.attributes.add("href", urlhelper.action(item.action, item.controller));             a.innerhtml = item.text;              li = new tagbuilder("li");             if (item.getselected != null && item.getselected(action, controller))                 li.addcssclass("sel");             li.innerhtml = a.tostring();              listbuilder.append(li.tostring());         }          ul.innerhtml = listbuilder.tostring();          return ul.tostring();     } }  public class simplenavitem {     public string text { get; set; }     public string action { get; set; }     public string controller { get; set; }     public func<string, string, bool> getselected { get; set; } } 

now 3 other page inherit site.master example about.aspx

<%@ page title="" language="c#" masterpagefile="~/views/shared/site.master" inherits="system.web.mvc.viewpage<dynamic>" %>  <asp:content id="content1" contentplaceholderid="titlecontent" runat="server">about</asp:content>  <asp:content id="content2" contentplaceholderid="maincontent" runat="server">      <h2>about</h2>  </asp:content> 

now have master page named main.master want site.master should inherit main.master page..so should
