Would be good to know about them however 😉
In my case I am writing a front end form which loads a field group and I do not want include certain fields if a certain condition is not met.
What I ended up with is using the acf_get_fields
function to get all the fields from a group into an array, then run a foreach on the fields and on certain fields run a check each field.
So if the admin is reading these forums, it would be good if this function was in the documentation, it would have save me some time 😉
Cheers
