You are right, the collapsible code itself is JavaScript code, previously I took it from wikimidea, but I am not certain that it's the best fit here on wikia.

Also for making navbars like Zeldapedia you mentioned, you would need additional css code. That is if you want to have readable customizable templates and not a book long ones ;)
