Hi,

How to display custom fields to a certain category?
So the moment some select Vehicles and then Cars, the custom fields should appear for that category.
At the moment when i select car subcategory, custom fields are shown but all of them ( trucks, motorcycles etc ),
which is irrelevant to user when posting a car.

Or is it possible to disable categories and then post direct from plugin types ?


Thank you

I have created only one category, and then preselected that category and i have hidden too. So when someone goes to publish page, then you will have the custom fields shown automatically. Copy and replace the code in item-post.php

Easiest way is to trigger change on category (select first value and trigger change).
