expandNode question

[webdept]

I am evaluating CoolTree for purchase. I downloaded the free version and have a question. I am looking at the Graphically Rich sample named sample.php.html.

At initialization it uses:

var tree1 = new COOLjsTree("tree1", COOL_NODES, COOL_TREE_FORMAT);
tree1.expandNode(0);

And when the page loads, the first node opens. How do I change which node opens when the page loads? Shouldn't setting tree1.expandNode(0); to tree1.expandNode(1); open the next node? It does not.

Please explain how to selectively open a node when a page loads.

Thank you in advance.

Thanks for your attempt to answer my question but your link does not provide the info I need to selectively open a node. I was hoping that a Cooldev developer monitored this forum and could provide specific details.

I am that developer (look into the script's code - I am the author of the current version). And that link contains paragraph that starts with "You can toggle specific node...". In COOLjsStandard all nodes initially are collapsed, and "toggle" actually means "expand".
