A great form plugin

I had to move from Caldera Forms, which I think is still better a bit as it offers more in the free version, like conditional logic and more versatile drag and drop interface. The learning curve is a bit steep with Ninja Forms if you want to nicely arrange and format your forms: you have to do some CSS, except if you use the paid version. All an all, I am still really satisfied with the plugin, it is easy to use it on a multilingual site and it just works.
