Hi tulio,

I meant that the codepen provided is invalid because nothing is seen in it. The issue is that the editor is not implemented as in the sample I referred to and that the data source is invalid. While the sample binds to beverages.json, your columns do not and the Grid is empty without any data loaded. It looks like that you want to use the grid in unbound mode as a spreadsheet and add dropdownlist editor to it. Is that right?

Best regards,
