If you get COBALT, you dont need anything else anymore.
Nested categories, unlimited fields per article, flexible layout, comments, rating, etc etc ...
Only your imagination is the limitation what you can do with this extension.
Not only the product, also the support is outstanding. While experiencing some difficulties with my own import script, Sergey immediately went out of his way and fixed my problems within minutes. Free of charge. Thank you very much for your support.
The most incredible fact is that this high quality component is absolutely free as well.
I bought several add-ons just to support this extraordinary product -- worth every cent.
5 stars are not enough to rate this component.
