The event menu is a right-click menu that is fully configurable and can be enabled under the Features tab. You have four options:
Default: Shows edit and delete menu items.
Custom: Allows you to add one or more custom menu items and specify on an event level or global level if the default edit and delete menu items should be enabled.
No menu: Disables the event menu.
Custom menu items
When "Custom" is selected under Features, you can define your own custom menu items. Only the caption is required. You can also define an expression that determines if the menu item is enabled (visible and interactable) for a particular event (or globally).
