Is there a way to find what extension is use on a wiki page?

[SecretUser]

Hello,

I would like to know if it's possible to find out which extension is use for a specific thing.

I have naviguate a lot on wikipedia and sometimes I found some functionality that I would like to implement on my mediawiki.

For exemple in : https://fr.wikipedia.org/wiki/Rivalité_entre_l'Angleterre_et_l'Argentine_en_football#Articles_connexes

I would like to know what extension is use to make the display/hide of the green block.

If you have an idea or solutions, it could be really helpfull.

Thanks by advance.

That isn't an extension, it's built into MediaWiki. See https://www.mediawiki.org/wiki/Manual:Collapsible_elements for more details on how to use it.

Thanks @Skizzerz !

I have use this function as an example but my main preocupation is: If I find a functionality, have I a solution to find out how it's done/set up?

Check Special:Version on the wiki to see if they have any extensions that seem related to the feature in question, and then searching mediawiki.org about it is your best bet. There's no one answer that will 100% work for any arbitrary feature. For things that appear in the page itself, editing/viewing the source of the page may help as well (you may need to go through some nested template rabbit holes first though)

Thanks for your time, I'll do some more in-depth research!
