DHXTree DataProcessor

In DHXTree v1.6, how to add additional parameters to dataprocessor url?

If you want to have it as static parameter, just add it while dataprocessor initialization
    var z = new dataProcessor(“my_url.php?param=some”);

It can be changed at any moment

If you need to have an item specific value - you can set it as userdata ( all item related userdata send to server as additional params of request )
