I would like to ask if it’s possible to display the number of results next to each filter in real-time, similar to what you can see in the attached image.
Unfortunately not yet – but in a future release this is definitely going to be implemented.
We decided not to bother with it yet as it is a major performance hit. I know many plugins have this feature, and it works greate until there is 1000+ more products, then it goes sideways very quickly.
