How to check if a menuItem is visible?

I am currently testing a WPF application and getting all menus and submenus.

However, when I use the WPFmenu.Items property, it is giving me all submenus which are not visible on the actual GUI.

Is there a way to check whether a menuItem is visible? 

I have checked for Enabled property and it doesn't work as I expect it to.

# menuItem - TestComplete MenuItem Object

# menuObj - User-defined class rssMenu 

def getSubMenuRecursive(menuItem,menuObj):
     # If a menu, has a submenu get the number of submenus
     if (menuItem.SubMenu != None):
          subMenuCount = menuItem.SubMenu.Count
     # else return, there is nothing to recurse
     else:
          subMenuCount = 0
     # Recurse to find all the linked subMenus
     for i in range(subMenuCount):
          subMenuItem = menuItem.SubMenu.Items[i]
          if (subMenuItem.Enabled == True):
          subMenuItemObj = rssMenu(subMenuItem,menuObj)

          # I want a submenu to be added to menuObj.submenu[] only when it is visible on the application
          if (isVisible(subMenuItem) == True): 
               subMenuItemObj = getSubMenuRecursive(subMenuItem,subMenuItemObj)
               menuObj.addSubMenu(subMenuItemObj)

     return menuObj

---------------------------------

# User-defined rssMenu

class rssMenu():

     def __init__(self,obj = None,parent = None):
     self.name = obj.Caption
     self.parent = parent
     self.subMenu = []

     def addSubMenu(self,obj):
          self.subMenu.append(obj)
          return
