How do I delete a Group Set?
Canvas recently introduced a new page design called the New Canvas User Interface (UI). Depending on your Canvas view, your page design may vary from the images shown in this lesson. However, the functionality and location of the components remain the same.
As an instructor, you can delete an entire set of groups. However, deleting a group set also deletes all the groups within the group set.
Open Group Set
Click the View User Groups button  or an existing group set .
In the group set , click the Group Set Settings icon , then click the Delete link . A popup window will appear in your browser.
Note: Deleting a group set also deletes all the groups within the group set.
