I spent 2 hours testing various form components and I’m glad I found and bought this extension (Pro version) because of these “nice to have for me” functionalities:
-All form elements I need in one panel
-Auto generate form layout (4 layouts)
-Multiple File upload with form
-Backup & Restore
-Easy and clean install on Joomla 1.5.3
-Customizable user & admin emails after submission etc.
At the moment I don’t know how is the technical, but so far it looks I’ll not need it.
Go test it at least is my recommendation.. I’m sure you’ll find more interesting things
And of course check the price ..it’s not bad at all :)
