How do I open and close weeks?
Turn editing on.
Take a look at the eye located at the top right corner of each week. Click the eye to either open or close it.
The following image shows an open week.
Here is the same week shown as closed (the open eye from the previous image has been clicked causing the week to close). Notice how it closed the eye for all of the content in that week. Also notice the change in color. The content has changed to a red/brown color.
