This option only supports the single and multiselect Filter types of taxonomy-based filters.
Enable product counts display for the terms of the current filter. The product count value will be changing with each new filter application, to reflect the amount of products available in each filters’ combination.
A caching mechanism and other technologies are in place to ensure the smooth functioning of the product counts management. Still, we would like to draw your attention to the fact that this option puts a substantial additional load on your server. If you are on a shared hosting plan and/or run a shop with very large amount of products and many filters, please use it only on the filters that really need it.
