I have a Text Area input for users in an application that lets them put down notes. this is shared between all users. Is there any way to make the input so that it only allows new inputs and not let users delete or modified the data that's already there to prevent them from modifying other users notes? I guess you can just disable input all together and just have a concat or something in the backend after the user submits but I would have to show the previous notes also. how would you make it seem like one text area? is there a better way of doing this?
