Hi, I noticed that the default navbox on my Wiki is a little basic (only having two fields -- header, body). I'd like one that is similar to that on Wikipedia which I believe I need lua for. How do I do this? I know it can be done on Wikia sites (e.g., on the minecraft Wiki I see a lua-based navbox is used ) but I'd like some help with doing so. I have a programming newbie so please just give me simple step-by-step instructions.
