After you file

I am referring to the navigation links on the left side of the page.  Perhaps my wording could have been better.  For example at the top of this webpage I see:  Discuss, Discover, Support.  If I hover over Discuss I see "Child" or submenus: Community Basics, Connect with Others, Top Contributors, News & Announcements.   I cannot get the submenus to display for "Tax Home" after I have logged in and in the process of completing my return.  Thank you for responding.
