Thanks for that plugin.
I have a custom post type with several parent categories. Each category has several sub-categories.
How can I show as a dropbox in the form at first, only the parent categories and then, if one selected, open a second dropbox containing the subcategories.
You are talking on your site of Free premium add-ons (coming soon). What kind of add-ons are you talking on ?
Yep, limite post to a date, upgrade post to another subscription pack. And maybe the harder, when an user update a post, put that new post as pending moderation but STILL let the old post visible on the site.
