After trying six other free form-building extensions and having no luck creating what I wanted to see, I purchased Blue Flame Forms. It is such a small price for such a wonderful component! What a time-saver compared to the others! And it is much more intuitive, easy to configure (installation and configuration is a bit different from usual so read the doc) and the created forms are beautiful. Please note that you have to upgrade to J1.5.15 if you're using an earlier version of Joomla. Tip: Do the update first - I used the free extension Joomla Update Manager - and configure the update manager parameters to Default 1.5 Extractor. Then everything will be ultra-smooth. I wish I'd bought Blue Flame Forms a long time ago! Excellent, excellent extension!
