Hey Jeanie,
Thanks for reaching out to us!
By default, the event widget will show the calendar and have the ability to switch between months. If there are events for a day, there will be an indicator on that date and by selecting the events for the day will be listed below the widget.
Beyond that I’m not sure what you’re looking for with “full functionality”. If you would like, you could purchase the plugin to test and if it’s not what you need, you can get a refund as long as you request within 30 days of purchase.
Let me know if this helps.
Thanks!
