Hello, Dawid,
We do not currently have this feature and do not have plans to implement it at this time. However, we do have a separate widget for filters (although it is not Ajax) – https://xstore.8theme.com/elementor/demos/minimal-fashion02/product-filters-element/ For example – https://xstore.8theme.com/elementor/demos/book-store/ and https://xstore.8theme.com/elementor/demos/car-parts/ Here you can find more our elements – http://xstore.8theme.com/elementor/demos/minimal-fashion02/design-elements/
You can post your request on our Taskboard at https://www.8theme.com/taskboard/. If it receives enough votes from other customers, our development team will consider adding it in one of the upcoming updates.
Kind Regards, 8theme team
