I need to be able to select multiple Events in the TimeLine.
I know one way would be to get the Min/Max Values from the Zoombar. But would it be possible to drag with a selection shape (i.e. rectangle) in the TimeLine and have all events in the shape selected?
For range selection is used the Zooombar. If you want to add rectangle selection to the Timeline, you can request this as official feature here:
