Thank you for the comment. What you describe is a feature that needs hours of coding I am afraid. WE can’t guide you do this. You need a skilled developer and to be honest, I am not even sure if it can work with AJAX search in Properties List – as you have on homepage.
We usually take custom work requests, but right now we can’t review this as we’re fully booked. You can contact other developers to estimate this as the code can be changed by any good developer.
