Hi merdjpatts,
If you want to bind it from JSON coming from PHP, make sure that you create and bind the tree when the data is already loaded into the jqxDataAdapter. You have 2 options – to set the async: false of the source object and use the code from the sample. The second option is to initialize the jqxTree and set its source property to point to the jqxDataAdapter instance in the jqxDataAdapter’s loadComplete callback. The loadComplete callback is called once the data is downloaded from the server.
