Lets imagine we have the following categories in WP:
- /shop/jeans/black
- /shop/jeans/blue
-
/shop/jeans/white
-
/shop/t-shirts/black
- /shop/t-shirts/blue
- /shop/t-shirts/white
What I need is to create virtual categories that can show content from certain given ones, for example:
- /shop/clothes/black
will hold content from /shop/jeans/black and /shop/t-shirts/black showing only black clothes.
I know I can virtually join categories content by custom links like
- /shop/jeans,t-shirts
but it is not useful.
I also know I can use tags. Also I can add content to multiple categories.
All that don’t work in my case.
Is there a way to organize categories themselves into categories?
There are plenty of plug-ins at WP’s repository exactly for this need, just search for custom taxonomy. I would recommend Simple Taxonomy. This plug-in haven’t been updated for more than three years but it seems to be working as expected with WP 4.4.2. It is quite powerful and totally free.
