Unfortunately, we don't have an option to change the order directly; it will require custom work. 

However, you can use the following custom code to change the order of courses based on a custom field like course_order. You can add this code to your child theme’s functions.php file: https://codeshare.io/9bZeOV

For this custom order to work, you need to add a custom field named course_order to each course:
  1. Go to LearnDash LMS > Courses in your WordPress dashboard.
  2. Edit each course.
  3. Scroll down to the Custom Fields section.
  4. Add a custom field named course_order and assign it a value (e.g., 1 for the first course, 2 for the second, etc.).
  5. Save the course.
If you don't have custom field support enabled, you'll need to activate it for your LearnDash courses.
