Vue Agenda Bulk Actions

Multiple event selection can be turned on with the selectMultipleEvents option. Selecting multiple events can be done through user interaction with CTRL/SHIFT/CMD + click or programmatically eg. click of a button or 'select all' checkbox.

Bulk operations like delete, update can be applied the selected events. Things like deleting with the backspace or delete buttons work out of the box but custom actions can be also applied. The selection can be easily retrieved and updated with the selectedEvents option and the selected-events-change event.

Custom actions can be performed with external buttons or with context menu activated on right-click.
