The calendar can display site, course, group, user and category events in addition to assignment and quiz deadlines, chat times and other course events. Note the colour coding on the screenshot below.
- New events may be added either by clicking the button or by clicking into an empty space in the desired day in the calendar.
- When adding, editing or deleting events, the event displays in a pop-up window.
- Those with permissions to edit categories may also add category events as here:
Events created manually may be dragged and dropped to different dates, as can Feedback activity, Assignment activity and Choice activity events. (For activities, the dates will then change in the activity itself when dragged to a different date on the calendar.)
