WordPress Posts are automatically categorized by the date in which they were posted.
You can change the “Publish Dates” for your Posts (and custom post types like slider images,testimonials,faq etc.) in the order you wish to have them display.
- Open your WordPress Dashboard and click custom post type which you want to edit.
- Locate the Post you wish to edit and click ‘Quick Edit’.
- Change the Post Date to any date you wish. Posts with the most recent date will appear first so changing it to an older date will move it down the post order.
