I'm new to the WP settings API, and a fairly novice PHP developer. To get started I followed this great tutorial
and customized it to my needs. and all is working nice and neat.
Unfortunately I could not find online reference to creating user dynamically repeating fields, such as an "add new slide" to a slideshow. I feel like I'm really close, but I can't figure how to register new content. I'll be thankful for suggestions or pointer in the right direction.
