Sorry I didn't find this post sooner!

The difficulty is that opening a node requires a request to the datasource to figure out how many children there are. So it is not a synchronous process. For example, to open a child of a child, you have to call my_table.datasource.get('datasource').toggle() three times, and each call must be nested inside the completion function of the previous call.

If all you want to do is open a top-level node, call my_table.datasource.get('datasource').toggle() with the node index (as an array, e.g., [3]).

I will investigate whether or not it is possible to pass the open state in the data.

Hi John,

Not sure I should reopen this old post but question is the same. I see your notes regarding the openNodeKey as mentioned in your response, but fail to find any mention of this in any documentation. I cannot get it functional. Can you advise if this is still the proper mechanism and perhaps post back a simple sample of same ?

Many thanks

Vince


I just pushed an update which allows the initial state of openable nodes to be set in the data. Check the updated yuidoc for "openNodeKey".
