How can I use a topbar design associated with a different sidemenu design [Ultima Template]?

I wish to use the topmenu design which is associated with sidemenu modes of "overlay" or "static".

Here's the topmenu design I want:

I looked around in the code but couldn't find any property which can be used to specify topmenu design.
