There are over 60 module positions with this template that are collapsible (if no modules are published to the position, it will not appear).
Logo, Menu, Date, Text Sizer & Scroll to Top Elements:
These are non-standard elements that are injected into the template grid structure, if enabled via template parameter. The logo element is injected into the header-a position; the menu into navigation; the date into top-d; the text-sizer into feature-f; and the scroll to top bottom in copyright. They are inserted in a stacked fashion into that position. For example, if there are modules published to the header-a position, they will appear in the same column as the logo, just place below it.
You can change the positions of these elements at Extensions → Template Manager → rt_reaction_j15
