You can change the default event filter on your portal (calendar) at any time. The most popular options include "All Events" and "Virtual Events".
A primer is below:
"All Events" includes all in-person and virtual events within the specified radius.
"Virtual Events" will only display events that have been designated as virtual, and will include any within the specified radius, as well as any nationally relevant virtual events.
This default can be changed on your admin portal page in the "Configuration & Display Settings" section, in the "Default Page Filter" field.
