Hi Bernhard,
Thanks for the info and the links to jQuery tutorials. I haven't had to learn jQuery yet for any prior projects, but it will be very useful for my current project. The site I'm building is a resource directory of information for teachers in higher education. I'm trying to keep it as plain vanilla as possible, because I will need to hand it off to someone else in the future and I won't know who that person is or what their skills will be. It's a risk doing it on Processwire instead of Wordpress, which is what I was originally planning to use, but PW is just so much better. And now that I've found it, there's no going back. The project got so much easier with ProcessWire, even with the time I've put in to learn the API, build my own php templates, etc. It's definitely worth the effort.
Best wishes,
mdp
