Adrian, thank you for sharing these example. I copied and pasted your navbar code (except the material following the list item 'Start Page', I remembered to close the <ul> that starts before "Start Page") and it gives me a Navbar, but with two problems:
(1) The text "Start Page" is not aligned with brand name "Roles Examples App" (the former appears on the right of the latter but slightly below vertically).
(2) The navbar hides the heading of the template that follows (that is rendered by the iron-router), even though the template starts with <div class="row-fluid">, and hence I expect it to give a new row.
As you said, version could be an issue? How do I check it? Also, should it not be the same since I am using meteor add bootstrap.
Thank you.
