Hi and thank you for your reply. I managed to do some of the things:
I managed to add filter options and it works great so this is nice. But how do I remove the “search” button that is currently being displayed within the settings-area? You can check it out on live right now.
Also: If I remove a cpt from the index, is it possible to just “update” the index or will i have to reindex everything then?
Regarding #1: Not precicely, I am looking to display the results within each category-headline and only display 4 results for each group so 1 group won’t be too long in comparison to the other groups
