I found this plugin and it seems to be extremely useful, but i can't get how to make it work the way i need.
The problem: there's a post that contains several sections, each section requires a box with metadata (e.g. a list of airports with location, phone etc of each in the boxes).
I know how to create fieldsets (thanks to this solution) but i can’t get if each of them has an ID, moreover i can’t control where exactly in the post the fieldset’s going to be output, so i (the client actually) need to use a shortcode for each fieldset.
Having spent hours googling i finally got stuck, i realize i have to get my hands dirty (or even bloody) to solve that but i have no idea where to start from. I’d appreciate any help.
