You've seriously saved the day!
I've tried a lot of components here. This one worked perfectly and I could actually understand it.
Basically all I wanted on my Joomla 1.5 website was the ability to create sub-categories within categories.
I didn't want to upgrade or use the sections.
This component did the trick. I had this up and running within 5 minutes.
I had spent hours on other components which were way over my head. I finally found this Gem that really saved my day and endless hours.
Take my hats off to you for developing this excellent component.
Thank you very much!
