Categories list whats beneath it

xanthos84 · July 2016

Hi everyone,

I am new here and I want to achieve this case:

Lets say you have

Category Heading
-SubCategory 1
-SubCategory 2

Now I want to click on the Category Heading and see all discussion from SubCategory1 & SubCategory2 (but it should not be allowed to be posted in Category Heading!)

How can this be done? I am not so safe into programming, so a little help would be grateful!

Thanks a lot!
