what you’re seeing there is the Terms for just the latest post in that archive.
And the reason for that is currently, the List of Terms is only applicable to a Single Post, and when applied to an archive the ID that WP fetches to retrieve the terms is for the latest post.
Today, you would need to write a custom shortcode to display the terms.
I can help with that if you require ?
I assume we are dealing with a list of child terms for the current parent archive?
Let me know
Yes, that’s right, I think the idea is to display the child categories using the grouped buttons. However, I’ve seen there are many child categories, so if there is a way to select specific category ID’s that would be the best way I think.
I also looked at how I did it before, and you can see it in this example – https://kitchenambition.com/cooking-school/
– was with tags not categories. So I see now why it’s not working in the way I thought.
