Pretty much the whole code is in there. It have good and bad sides of using the code like that. For example a bad side is if the wiki make some upgrades and the code is no longer working with the new version, if you are using imported script like the line I showed, someone will fix the code at dev wiki and it should work again. A good side is that the wiki don't have to load the outside script, but if something gets broken, you have to fix it yourself (although it can't be messed up by someone else too, but the code should be locked at dev wiki to prevent that).

The code is from "Collapsible tables" until "addOnloadHook". And I think after that for the Dynamic Navigation Bars is again something similar. If you haven't added it for something specific. But like I said, I'm using on few wikis only the line I wrote in my previous post and all my show/hide are working.
