OrgChart collapse event

[Augusto Gomez]

Good day, I'm building an OrgChart that starts with some of the nodes
collapsed. My problem is that I need only one of those nodes to be
expanded at a time, so I'd like to know if its possible to collapse,
for example the nodes B, C, D after the node A have been expanded.

I'm using the collapse event but I'm unable to know:

1. If the node its being Collapsed or Expanded. Because the collapse
event triggers on both.
2. Wich node (row) of the chart is being collapsed

thanks in advance.

The collapse event contains all both the state change (is the node being expanded or collapsed) and the row index:

google.visualization.events.addListener(chart, 'collapse', function(e) {
    alert('Row ' + e.row + ' was ' + ((e.collapse) ? 'collapsed' : 'expanded'));
});

Thanks for your advice and the fast response, however e.row always
returns "undefined" I dont know if that may be caused for preparing
the data from an Array through arrayToDataTable(). I'm gonna modify it
just to check it aint the cause. Thanks!

That's probably a bug.  You can get around it for now by using e.a instead.
