Hi again Sakis,
Sure, I am happy to tell you more about those "Composable sources" or "Composed sources".
Actually it is a feature that ships with Essentials by Zoolanders. It was released ~6 months ago :
https://zoolanders.com/blog/essentials-2-1-for-yootheme-pro-composable-sources-yootheme-pro-4-2-and-joomla-5-compatibility
It is really great because of course YOOtheme is already very powerful, but if you take the Grid element for example, you have typically "only" a few fields available:
- title
- meta
- content
- image
- read more
And sometimes (like on my website) you need more fields because you would like to have
- "First Name + Name" as "Title"
- or plenty of Custom Fields as "Content"
So Essentials by Zoolanders allows exactly that :)
Note1: another way to get as many fields as you like (with the layout that you like), which is then native with YOOtheme since last year, is Repeatable Column or Repeatable Sections. I thinks Elisa show it here (with a Dynamic Section for each animal): https://www.youtube.com/watch?v=gPrJvyAjhR8
Note2 : still another way to have more Custom Fields on a given field is to use Articles Anywhere Pro by Regular Labs, with something like {article id="ID" [year] [style] [whatever]{/article}
Actually you say that the source of your field is "ID" and then you select your prefix and postfix so that you get what I just wrote
