How can I get Notes to also sync to my wife's Apple ID the way Calendars and Contacts can?

Thanks for your reply. I was under the impression sharing wasn't the same as syncing, as I want both of us to be able to edit the note. I see now that editing can be done on a shared note. Thanks for pointing me to the article where that was made clear. You can't share locked notes, which are of course, the very notes I want to share ;-) I guess for security purposes you don't want someone with physical access to your phone to share a lock note to themselves and then be able to open, but I would think it would still require the password. Anyway...

Also, you can't share the folder "All iCloud", meaning all notes, which is also exactly what I want to do. So, apparently I need to unlock my notes and put them into a subfolder to be able to share. Seems like syncing (the way contacts and Calendars do) would be a much simpler solution but one that Apple has for some reason decided is not the way to handle notes.

Thanks for your reply! My reply to the other poster outlines my misunderstanding of the difference between sharing and syncing. It wasn't working for me at first because you can't share locked notes and you can't share the "master" folder of all notes.
