Hi weldridge,
1. You can initialize the content only in the initContent function during the initialization process. There is no built-in API for dynamically changing things in the jqxLayout. After you initialize your content in the initContent function, I suppose that you will be able to access it through jQuery selections by ID.
2. It’s included in the source code download package. It’s not a product, it’s a file required for data export. On the API docs for a particular widget which has data export, you will find out how to replace the default URL with the one where you hosted the file.
Best Regards,
