EditableGrid is an open source Javascript library aimed at turning HTML tables into advanced editable components. It focuses on simplicity: only a few lines of code are required to get your first table up and running.
When I compare the simple xml demo with the json demo, I've noticed that the json demo does not seem to support the drop-down ability to change country. In the json version you cannot edit the country at all. In contrast the xml version allows you to change the country by clicking it, which gives you a drop-down menu.
I'm not sure if this is a problem with the demo, or a fundamental problem with json support in editablegrid
This appears to be a simple problem of not including the jquery libraries in the index.html for this example. The drop down box required jquery to function correctly.
