I need to add custom fields to a Page.
I created a Plugin that manages the Categories/SubCategories. But now I can't find how can I show the category field on the "Add Page Modal" view without editing the original file inside Ip/Internal/Pages.
As the override folder in themes is only for views is there a way to override/extend internal controllers?
E.g: - adding multiple tags, categories, etc. - A widget that filters the pages that have the selected tags (!= alias, because is not unique)
Thanks!
