This is an absolutely brilliant extension if you are looking for an extensive, drill down filter for your content that doesn't modify Joomla core files and doesn't duplicate your content. This is a very well thought through component that is, once you spend some time with it, is very easy to use. Once you set it set up, it's all like a fairy tale from there on. I have never had a Joomla extension exceed my expectation before. I almost given up on getting a filter for my workout routines until I stumbled upon Fields and Filters. It didn't just work, it worked better, smarter and had more features than I ever expected.
There is something that has to be said for the support you get for non-commercial extension: Wow. I happened to use the latest Joomla so it wouldn't show the option in the back-end, it was not compatible. I sent a message to the developer hoping that maybe he'll know the exact issue so I could start looking into it, but I honestly didn't have high hopes of getting an answer. I got one just a few hours later and with a fix attached! Absolutely brilliant support, helpful and friendly and fast. I have never had a better experience.
