Hi,
thank you for that info. I changed to drop-down multiselect layout. Just qestion. Can I set by CSS that categories will be visible on default without need to click on search filed (see attached screen).
Cahing will help a lot but my current hosting is limited by file usage and I am already almost in limit, so extra cached files for each queries are not possible for me now. Is there any chance to cache only filtering? For example by some another caching plugin?
