You’d like to have events that start in the past be read-only, but events in the future need to be editable.
This functionality is implemented as two acitons which should be used together.
The On Event Click action dynamically makes the pop-over read-only and the Before Save Action prevents past events from being dragged and dropped.
|On Event Click
|Open in new window: No Prevent default action: No
|Before Event Save
