Hello! Sorry for my English, it is not my native language.
I have a ‘data tree’ as categories (basically many categories with many subcategories) and now that there are too many, it is tedious to create a new category and assign a parent category to it because maybe there are many categories starting with the same letter, then in the input select you must be searching a long time.
I don’t know how I can do it, if there is any plugin that can help me, etc.
The only thing I can think of is to try to change the input with some JS library because I can’t use ACF or similar because all the logic is already there using the native WordPress input.
