Configuration options include the block title, the section number, and the id of the course the section belongs to. The block/section:editcourses and block/section:editsections permissions control who is able to set the section and course ids. Administrators and Managers have these permissions by default.
The course id selects the course containing the target section. By default, the current course id is used. When on the main course page, the course ID can be found in the URL: A url of myMoodle.edu/course/view.php?id=42 indicates a course id of 42.
In course formats with sections, such as the Topics and Weekly course formats, the sections are numbered from 0 to the total number of topics/weeks. A course with 3 topics or weeks has sections 0, 1, 2, and 3.
Social course formats have only one section by default, section 0. This section is displayed in the Social activities block.
The front page also has a section 0, which may be displayed in the main area or in the Main menu block.
