Several filter hooks are available within the NGFB plugin to manipulate text (title, description, content, etc.) and arrays (tags, open graph, etc.).
If you’d like to customize and integrate additional features into the NGFB plugin, we offer custom development services. Submit a ticket to describe your requirements, and we can give you an idea of the expected time and cost to develop your custom feature(s).
