Hi,
I have an ACF date field in a CPT.
I want to add a dynamic filter on that custom date field, a dropdown, that will fetch all the values dynamically, but will display only the year portion of the date.
Not out of the box, but very likely possible via a small custom code snippet – but it depends on the exact field type, values and the field name as well.
If you have a drop-down field setup already, let me know (either via a link or back-end access), I will take a look at how the populated values look like, and go from there.
