Here's how to do it with a "select" event listener:
google.visualization.events.addListener(chart, 'select', function () {
// get the row of the node clicked
var selection = chart.getSelection();
var row = selection[0].row;
// get a list of all collapsed nodes
var collapsed = chart.getCollapsedNodes();
// if the node is collapsed, we want to expand it
// if it is not collapsed, we want to collapse it
var collapse = (collapsed.indexOf(row) == -1);
chart.collapse(row, collapse);
// clear the selection so the next click will work properly
chart.setSelection();
});
