Hi Team, I support a site which has a few issues with regard to small screen function. The little yellow box with black bars icon (for compressed nav bar) seems to have no content? When I look at the code templates I can see the ordinary coding for

but I also use bootstrap a bit and cannot see any of the classes that seem to populate it present at the moment. My question is: does umbraco magically produce this from some other method or do I have to code the appropriate elements myself? Thanks, Paul
