Thank you for answering.
I tried it, but without luck.
I added a Option "Show All=22" to the field art_created.
Under Conditional States I have configured this:
The Result is that all articles are shown, independant what option (Show All, Published, Unpublished, ...) I am choosing in the Dropdown Menu. Filterin doesn't work anymore. The Dropdown field itselfs remains always blank:
Where is my mistake?
Is there another solution? I want to have a similar possibilty to filter categories (is working) and add a "Show all" Option. But I can't add options to the field
Article Category Id.
