Calendar events can be extended with custom attributes. Any data that you want to consistently track against events can be created here the same way you might tie an attribute to a user or page.

The is_featured attribute is a simple checkbox attribute that you can make manually which the Event List block can use for filtering on your site.

Once you’ve made a calendar you can pick the calendar you’re viewing from this drop down. You can also add new calendars, delete a calendar, or edit the name of the calendar from here.

Categories are tied to events within a calendar. Categories are pulled from the Topic Trees which you can manage from System & Settings, or by typing “Topic” in the Concrete search bar.

An event may be in multiple categories.
