This code creates a shortcode [ld_course_steps_list] to display a list of lessons, topics, or quizzes in a LearnDash course (without links).
Usage:
All Steps: [ld_course_steps_list course_id=”123″ type=”all”]
Lessons Only: [ld_course_steps_list course_id=”123″ type=”lessons”]
Replace 123 with the course ID.
