Hi Dekket,
Not in the plugin no.
I suppose you could highjack the click event on the filter button.
Basically:
1. highjack the click event.
2. Trigger your own AJAX request which loads the same filter page and take out the results and return to your JS as an html string.
3. Replace the dom element containing your list of posts with the one returned from the AJAX.
I’ve seen some plugins do it this way and maybe BTF will too in the future but right now you’d have to do it yourself 🙂
Best of luck!
