You can access the module in Management > Settings > Events > Event cancellation reasons.
In the top right corner of the screen, click the button with the “+” icon.
In the dialog that appears, enter the Name of the new event cancellation reason.
Set the Note field, which the user may – or must – fill in when cancelling an event and selecting the given cancellation reason:
None: The Note field will not be shown at all.
Optional: The note will be optional to fill in – it will not be mandatory.
Mandatory: The note will be mandatory to fill in.
And then press the OK button to create the event cancellation reason.
Sorting: You can sort event cancellation reasons in the list using drag-and-drop. Grab the left edge of the row with the reason and move it to the desired place in the table.
Editing and deleting: Reason records can be edited or deleted at any time if the member has permission to do so. A deleted reason is unassigned from all cancelled events where it was stated.
Managing event cancellation reasons requires write permission in the Settings and Events modules.
