Thanks for the example code.
Let me provide a bit more details behind my question: I have nearly two-dozen categories, but there is only one top-level category and its three child categories from which I need to select.
For instance, I have a top-level “Location” category and three sub-categories. Rather than list all categories in the ACF select box, I would like to narrow that to only the four categories.
Again, thanks for the help.
