Advanced Custom Fields plugin integration

I can highly recommend using Advanced Custom Fields when creating custom fields. Codepress Admin columns works very well with ACF.

To answer your question:

1. Just create a custom field with ACF
2. Add a post/page/user/media which uses that custom field
3. Go to Admin Columns and add a “Custom Field” column
4. Select the ACF Custom Field you just created from the dropdown.
5. Optional you can also select the type of field; image, text, true/false etc.
6. Click publish/update and you are done!
