The Today.wisc.edu Page Element allows you to display events from the today.wisc.edu calendar on your site. Each set of events you want to include will need a tag, which you can set up at the today.wisc.edu site when creating your event. Once you have a tag, you add the URL (e.g. http://today.wisc.edu/events/tag/yourtag) for the tag to the Today.wisc.edu Page Element.
Below, you will see the Academic Calendar tag used on One, Two, and Three Column Content Displays.
Here is the same Academic Calendar tag in three columns. The right side has 5 events set to show, as opposed to just the 3 seen so far.
