Personalization for going to a submenu from the menu form(when we are in the main menu)

 I am using a personalization by which i am going from the user form to the responibility form giving me the responsibility attached to that user and from the responsibility form i am able to navigate to the menu form giving me the menu attached to that particular responsibility(i have attached the screenshot). Now when i am in the menu form i want to navigate to the sub menu attached to that menu.I know that to navigate between different forms global variables are used but now i want to navigate in the same form.
kindly advise me on the required personalization.
