Thanks for the reply millernegro. I've attached the json sample that I'm using in the code section. I've tried giving the name of the property that contains the data(in my case "glossary") as the query but no fields are displayed in the right, to drag and drop like in xml. Code:{ "glossary": { "title": "example glossary", "GlossDiv": { "title": "S", "GlossList": { "GlossEntry": { "ID": "SGML", "SortAs": "SGML", "GlossTerm": "Standard Generalized Markup Language", "Acronym": "SGML", "Abbrev": "ISO 8879:1986", "GlossDef": { "para": "A meta-markup language, used to create markup languages such as DocBook.", "GlossSeeAlso": ["GML", "XML"] }, "GlossSee": "markup" } } } }}[/code]
