How to display a category filter in WooCommerce?

Question

WooCommerce

How can I implement such a filter https://tesser.ru/catalog/keramicheskaya_plitka/?s... on Wordpress 4.8 (Woocommerce)
There was already a similar question on the support forum https://ru.wordpress.org/support/topic/ %D0%BF%D0%B...
But no solution was found.
Naturally, I ask for help not to “do it for me”, but where to look? Where to dig?
I do filtering through facetWp. There are no problems with products; it filters everything as it should, but what about categories?

Answer 1

At the moment, I have deduced the category to which the product belongs. But the problem is that there are more than one product in the categories and, accordingly, it turns out that how many products are in the category, so many categories are displayed the same))
