Exclude particular categories from Classipress listing pages
Is there a way to exclude particular categories by id's from categories directory? I don't want to show some particular categories on page.
I would also like to exclude ads assigned to these categories from showing in search results, archives, category ad listing pages and homepage ad listing and tabs.
I would like to remove categories 10,15 and 44.
I still want to allow any user to submit ads in these categories, but I don't want to show ads assigned to these categories and these categories itself.
Ads from these categories should be only accessible by a direct link leading to a particular ad.
Any help will be much appreciated.
