Hello, thank you for fast response. There was problem with cherry picker, that when I see category page for one category it processed custom fields also for another categories and it showed me Error too many keys specified; max 64 keys allowed.
And I cannot see anywhere in documentation how to set up custom fields. Just basic fields. I am asking because I have already created program to fill custom fields like I described above and I want to know if it can be used also for your component.
Thank you
