I'm trying to find a way to override the default expand/collapse behaviour when clicking on a Group element in a VisJS Timeline.
I'd like to allow other actions from the group contents, and invoke the expand/collapse action programmatically from somewhere else in the UI.
I'm been looking into the code in the v4.21, but I don't seem to find a way to override the _onGroupClick on the ItemSet.
Any suggestions on how to achieve this in the most elegant way? (trying to avoid monkey patching)
thanks,
