Select drop down from server side

I am trying to create a drop down box in the datatable for each row with specific option tags to the row. For example row1 may have options 2 and 3 where as row2 may have options 1, 2 and 3. I am using JSON to send the data from the server. After the option is selected I want to save it back to the server. I don't even know where to start. Any help would be greatly appreciated.

Thanks,
Jon
