If I understand you correctly.
You want a form on a single post page, and for it to filter and area on that page that would show results based on terms found that come from settings on that page?
That would require some very custom PHP coding in the single post template page, where you would determine which prebuilt form to use, and then load according to that code whichever form you would need. However, most display results methods require a fixed results URL, and for those that do not, I cannot see this working.
I am sorry, but with the current version of our plugin, I cannot see how this can work.
