Hi @rpk
I can’t give you an accurate reply for your first 2 questions as they are written a bit confusing, but casically, think of the repeater field as an XML table where the USER can ONLY create rows, not columns.
You define the columns (image, caption, link, etc)
And the USER creates all the rows of data
As for the licensing, you can use your repeater field on any website you create!
Thanks
