Hello, I followed the KB article referenced below. What I want to do is search by a forum category (Parent) and all of the forums that are under that parent category.
I don’t want the user to have a dropdown selection. So what I tried is doing it as
Type: Hidden and in the Hidden values I first tried adding the forum id for the parent category but that didn’t work. I then tried adding multiple forum ids separated by a comma. That didn’t work so I tried multiple forum ids one per line but that also didn’t work. For the operator I tried EQUALS and LIKE
Well, the hidden filter is treated as a single unit, single value, so it is not possible to add multiple values to it. You can however add multiple hidden filters, each with the separate forum IDs.
Then set the custom fields logic to OR here: https://i.imgur.com/hWu73vZ.png
In theory, if the IDs are correct, this could work.
