So, I was on the Pokémon Go wiki and found a template that I quite like (specifically, this one https://pokemongo.fandom.com/wiki/Template%3APokesearch)

Basically, it's like an in-page search function. Allowing you to search certain words on one page. I really like this idea, but can't quite figure out how I would make one. Any help?
