I am interested in buying this, but need to use it within a forum plugin, NOT regular wordpress posts.
Is there a forum plugin that is already compatible with ACF?
Is it possible to specify that certain fields will be required if used within a forum, but not when someone is creating a regular post in WordPress?
I am using bbpress and I can chose the 3 posttypes from the forum plugin for my fields so I’m sure when you put the ACF code into the template files of the forum it works as with all other posttypes:

Thank you, @herrfischer !
I’m totally new at this and haven’t found the instructions on how to connect ACF with bbpress. Where should I be looking?
Hi, no need to “connect“, ACF atomatically lists all your post types and since bbpress has 3 post types they are listed. Just copy your bbpress theme files to your theme folder (https://codex.bbpress.org/themes/theme-compatibility/getting-started-in-modifying-the-main-bbpress-template/) and put the ACF code to it.
