i’ve got question. I have file field added to my custom post type and I’d like to limit the extension to only “.js” and “.css”. Is that possible? I couldn’t find any information about it on forum or in documentation.
Thanks for the question.
This is possible in ACF PRO (v5), but not in the free version (v4).
ACF v5 will soon be released as a free upgrade, but not as of yet.
Hope that helps.
