I hope I can find some help or advice here regarding custom taxonomies auto-complete (maybe there is a ready-plugin but I am not aware of it).
I have custom taxonomy which have around 500 items. So when I admin user create new post and need to choose one or multiple item in add/edit post screen, he needs to scroll down and search through all of those items. It is a lot of time-consuming job.
Is there any kind of auto-complete possibility that can be done for custom taxonomy, similar to tag auto-complete option?
