With the Topic Custom Fields addon, the topic custom fields are displayed under the 'Filter by custom fields' in the Search/Filter form. I'm wondering how to configure the ordering that the fields appear? I tried changing the ordering in the Fields tab in the Topic Fields page in wp-admin, however when it is saved, the ordering reverts back to the order in which the fields were created.

I also tried using the filter hook, wpforo_custom_fields_filter, but can't get it to work yet. How to best resolve this?

Thanks!
