Featured Category or Special Category in WordPress
Is there a way to make a category that will show in all categories in wordpress?
For example, my categories in my website:
- Cat A
- Cat B
- Cat B1
- Cat B2
- Cat B3
I want post tagged in Category A will be showed also in Category B and its children. So when they check mywebsite.com/category/cat-b1 they will also find Cat A.
I do not really know how to code, but I always can follow steps. Thank you a lot for your help.
