In my App I have navbar with menu. In menu I have 3 dropdowns.

• for normal users
• for admins

Access is restricted but menus

I see your roles is static, because you check if(RoleId==1) so that user is admin. I think you can define roles like enum.

public enum UserRole
        {
            User = 1,
            Manager = 2,
            Admin = 3,
            //SuperAdmin...etc.
        }

Create base controller, add CurrentUser property. And when action execute take current user.

 public class BaseController : Controller
   {
      protected override void OnActionExecuting(ActionExecutingContext filterContext)
      {
         CurrentUser = db.GetLoggedUserFromDatabase();  // to use in controller
         ViewBag.CurrentUser = CurrentUser;             // to use in views
      }

      public User CurrentUser { get; set; }   
   }

Finally your controller implements BaseController:

 public class AnyController : BaseController 
{
       //in every action you have current user's details.
       //Already you know current users role. you can use it. for example:
       public ActionResult AnyAction()
       {
         if(CurrentUser != null)   //if user logged
         {
           if (CurrentUser.Role == (int)UserRole.Admin) 
           {
              //user is admin
           }   
         }      
       }
}

In views you can use ViewBag.CurrentUser. Cast it first then check role as in controller.
