I have to send list of trades in a form in a single message in chatroom. for each trade, there would be a checkboxes. User would select acknowledge trades partially (let's say 10 trades are sent and user select 4 corresponding checkboxes for 4 trades, and left 6 unchecked ). So when response is received, it's recieving name and value for trades which are selected at checkboxes. Is there way to get both (selected and unselected checkboxes information)?
