Hi there,

I am looking for an option in timeline to hide groups with no visible items. If you look at the frist group demo (http://visjs.org/examples/timeline/05_groups.html) and move + zoom the timeline to show only item 7, all groups remain visible despite group Alston and Lee has no visible items. Here is a screenshot :

It would be wonderful to autohide these groups because in my application I have several groups and they fill the screen however only a single item is visible in most of the cases.
