Hi @ventsimoll
Thank you for using Filter Everything plugin.
Cyrillic does not scare me, I myself am from Ukraine 🙂
In general function “Parent filter” should work for you, but you also have to enable option “Hide until parent selected” – https://prnt.sc/YZrgiAe1NOq1 for your Volume filter.
In this case if you select any Category that has products intersected with Volume filter terms, you will see Volumes. If the selected Category has not intersection with Volume filter, you will see N/A instead of Volume filter terms.
But if you need to hide whole Volume filter when the selected Category has not intersection with it, you have to use PRO version as it contains feature “Hide empty filter”
I hope this will be helpful for you.
