Whether this option is shown for events is set in the specific Event type.
Event types
Create and set up custom event types suitable for your organization. These will be assigned to individual events, which will behave according to the parameters set in each type.
When creating or editing an event in Management > Events. In the Basic information block you will find the Event content field.
The second way to fill in the content for each event is directly in the Member zone / mobile app in event detail > Attendance.
In the web version under the More > Edit event content button.
In the mobile app directly on the Attendance tab.
Attendance management
For events that have attendance tracking enabled, members can gradually sign up, giving you a real-time overview of who is attending and who is excusing themselves. You can then save the attendance, and it will be recorded in the team statistics.
To document the event content, the data needs to be exported. You do this in Management > Events > Export. The event content is shown in the export as a separate column.
To access the event content settings in Management you need write Permission for the Events module.
To access filling in the event content in the attendance of an individual event, you need to be a team manager of the given team or have Management permission for the Teams (at least read) module and at the same time for the Events (read and write) module. The access scope must be complete.
