In the creation of each new “article” is there a way to check that it is a unique slug? I ask this because of the off chance the editors create an article with the same title in two different categories.
That would also be possible if you add the categories via a field. Not sure what I’d do myself in this case, I’d probably put them all into one folder, particularly if I don’t want the subpages in the URL. In case it causes performance issues in the future, it will be easy to change the setup and move the pages into category folders programmatically.
