Well I spent a few hours trying to code like that site… I got very close too!
Long story short yahoo delivered me a result google didn’t
https://ww.wp.xz.cn/plugins/faceted-search/
Seems to work okay except with parent categories, which isn’t a big deal
Thanks a lot for you help
I will probably try and do it myself at my leisure, at least now I can launch the site i.e. tell friends and family about it 🙂
So thanks for that, I have no searched the first 3 pages of results.
It seems there aren’t any plug ins that would do this simple task, unless I want to spend a lot of money. They are designed for commercial sites.
I had a shot at copy and pasting codes into the functions (previous threads) and I managed to wipe my whole site, I had to delete the theme manually haha.
If anyone knows of a cheap plugin that would allow searching of multiple categories, that would be appreciated. Otherwise I will need to redo the categories on my webite 🙁
