Make Fields Apply Only To A Particular Category

[Meddysong]

I've set up a database with categories. What I would like to do is have some fields apply to only one of those categories, not everything else in the database.

How do I do that? Is it possible?

[opentype]

Yes. :-)

It’s in the category settings.

I must be really stupid today because I can't find anything like this. Where am I looking for these settings? I can find the individual categories and click on the pencil icon, no problem, but there's nothing like that there. Just the usual stuff about name, slugs, and listing and display templates.

Maybe there's something wrong with my installation of Pages, because the advice from here

doesn't work for me either. I can't see an option to select "Use Form Fields".

[opentype]

There should be a Form Fields tab in the category settings.

Got it - thank you! I had to create the fields, of course, to get that option. I thought that might be a problem so looked at a different database that already has forms and ... didn't notice it earlier, even though it was right under my nose
