Add and delete reminder lists on iCloud.com
All reminders you create are put into a reminder list. Organising reminders into lists makes it easy to keep your work, personal and other to-do items separate from each other. Each list contains a place for active reminders and one for completed reminders. See Mark a reminder as completed on iCloud.com.
