React map method Render Input dynamically change value separate fields

Question

I am got a loop data Array that contains more than 100 data and I am used map method to render it that are already defined the user can update only for the specific field have id and unique id I now need to be able to edit/submit them uniquely separate fields.All fields should be some default. At the moment, I haven't figured out how to differentiate them onChange causing the state to be the same on ALL fields. I need each field to update separately with its unique data and I am using react hooks Input Forms, rendered by the map. These are the forms I want unique update fields.

Please Give Any Idea that will helpful to implement or suggestion how to approach this I am new to react please help us

Thanks for Help

Code changed to update particular field in loop. if you want to other field to update you can follow the same.

pass ID and event to function

<input
    name="roomRent"
    type="text"
    value={roomData.room}
    className={classes.input}
    onChange={(e) => handleroom(e, i)}
 />

function to update particulat field value

  const handleroom = (e, id) => {
    const { value } = e.target;
    setRooms((room) =>
      room?.map((list, index) =>
        index === id ? { ...list, room: value } : list
      )
    );
  };

Improved code

export default function RoomListView() {
  const classes = useStyles();
  const [roomes, setRooms] = useState([...rooms]);

  const handleroom = (e, id) => {
    const { value } = e.target;
    setRooms((room) =>
      room?.map((list, index) =>
        index === id ? { ...list, room: value } : list
      )
    );
  };

  return (
    <>
      <div className={classes.root}>
        <Paper className={classes.paper} variant="outlined" elevation={0}>
          <div className={classes.layout}>
            <div className={classes.main1}>
              <Grid container>
                <Grid item sm={3}>
                  <div className={classes.roomType}>
                    <h4 className={classes.roomTypeContent}>Room Rate</h4>
                  </div>
                </Grid>
                <Grid item sm={9}>
                  <div className={classes.Roomcalendar}>
                    {roomes.map((roomData, i) => {
                      return (
                        <>
                          <div className={classes.Roomview}>
                            <div
                              key={roomData.id}
                              className={classes.roomavailable}
                            >
                              <input
                                name="roomRent"
                                type="text"
                                value={roomData.room}
                                className={classes.input}
                                onChange={(e) => handleroom(e, i)}
                              />
                            </div>
                            <div className={classes.roomSold}>
                              <p>{roomData.sold} Sold</p>
                            </div>
                          </div>
                        </>
                      );
                    })}
                  </div>
                </Grid>
              </Grid>
            </div>
          </div>
        </Paper>
      </div>
    </>
