The problem is worse when there are a large number of terms in the given taxonomy.
The ACF Extended “Taxonomy Terms” field allows for disabling lazy load, making it much faster to get to the end of a long hierarchical list. Unfortunately, the ACFE Taxonomy Terms field does not include the ability for the user to add new terms.
A taxonomy field that reproduced all of the features of the WP Core post editor taxonomy “components-panel” – including search and parent area designation among other user-friendly features – would be even better than an ACF Field that didn’t realy on lazy loading or an ACFE field that include the ability to add new terms.
Thanks for your reply, but I see now that the the post ID in parentheses may be added by a different plugin, Admin Columns Pro (AC), which among other things provides its own ACF integration.
AC apparently intercepts the post list before the ACF Post Object select2 field processes the list of posts. Where the same ACF field appears by itself – outside of an admin column – the post IDs do not appear. I expect that that list will be modifiable via the ACF hook you specify. To modify the one that appears in the admin column setting, it looks like I’ll have to kludge something up. On the bright side, an AC “get_duplicates” function and its application look like useful models for dealing with ACF post-list output.
I still haven’t found exactly where or how the substitution occurs. If and when I do, I’ll post the information here, just so that ACF users can get something out of this thread, which otherwise I’d see about getting deleted.
