Hi Larry. We use a custom theme so that we can alter what we need in the site header/footer. To modify the header, you need to alter this file;
It's then relatively straightforward to get extra entries in & do what you need.
Thanks Matt, that's helpful. I can get as far as adding static elements in there, but what about adding custom CSS for a dropdown. Would that go into css-custom.soy or can I include dropdown functionality right in nav/navbar.soy?
