Hi, I created a new custom post type for cars in wordpress.
Now I plan to create a page for the list of brands using taxonomy or meta data, but I want to see the available series of this brand after the user enters the BMW page, and after entering the page of each series , view different generations of cars.
How can I connect 3 separate fields?
So that in the admin panel, something is the same as the system that exists in selecting the province and city in online stores. After selecting the province, a list of cities under that province will be displayed in the side form.
