Further to my last comment above, here is a link to the LOOK-N-LEARN page at the top of this forum.
Look for the link to the LIST oF COMPONANTS for BOOTSTRAP 2.3.2
Clicking on that link you end up in the Bootstrap documentation.
Just scroll down the list on that page for the Navbar examples in Bootstrap 2.3.2
You can then follow the tutorial found in the Forum post in the same page which explains about adding Marketing Spots and a Jumbo size header container. As seen HERE
This works in Adaptable in Moodle 3.5 or 3.6
