[Catalyst] Example of a simple repeatable field and button

[Florent Angly]

Hi list,

I have created a small Catalyst webapp that uses a form that is based on 
a FormFu YML configuration file. I would like to have some repeatable 
fields, along with a button to click in order generate more of these 
fields on the fly.

I have read the Catalyst tutorial, the FormFu documentation, and I have 
some basic repeatable fields, but I seem to have problem with the logic 
of how to generate more repetitions of these fields from the 
webinterface. I don't even know if using a button is the most elegant, 
recommended way.

So... if someone could post a simple example of that, it would be great!

Thanks,

Florent
