I have a nested list and the elements within nested list link to pages which are in a tabbed format   

like 

  Homepage (List)--->Nested List(HREFs to pages)---->Tab1       | Tab 2       | Tab3

                                                                                Href1        Href2        Href3

Now the issue is when i reach my tabbed pages ,i need to have a back button in header which  navigates into nested list  directly.

If i just try a normal "back button" , it will lead me to last tab visited .

How can i achieve the functionality?

Thanks in advance,
