In materia-ui table. When I click the button to expand the row, it expands all rows. How can i make only selected row will expand?

Question

Row Click event expands all rows in the data table to display inner data of all rows

Expand button click expands all rows instead of selected row. Every time I'll click the button to expand the row1, it will also expand the second row. How can I fix this where only that specific row will expand?

 <Table stickyHeader aria-label="sticky table"> <TableHead> <TableRow hover> <TableCell>Title</TableCell> <TableCell>Created Date</TableCell> </TableRow> </TableHead> <TableBody> {data && data((index) => ( <TableRow hover> <TableCell> <IconButton aria-label="expand row" size="small" onClick={() => setOpen(!open)} > {open ? ( <KeyboardArrowUpIcon /> ) : ( <KeyboardArrowDownIcon /> )} </IconButton> </TableCell> <TableCell component="th" scope="row"> {index.title} </TableCell> <TableCell component="th" scope="row"> {new Date( index.createdDate.seconds * 1000 ).toDateString()} </TableCell> <TableCell colSpan={6}> <Collapse in={open} timeout="auto" unmountOnExit> {index.text} </Collapse> </TableCell> </TableRow> ))} </TableBody> </Table>

Answer 1

I was able to add the index to open function and allow only selected row expansion. It works as expected and below is my modified code

 <Table stickyHeader aria-label="sticky table"> <TableHead> <TableRow hover> <TableCell>Title</TableCell> <TableCell>Created Date</TableCell> </TableRow> </TableHead> <TableBody> {data && data((index) => ( <TableRow hover> <TableCell> <IconButton aria-label="expand row" size="small" onClick={() => setOpen(open === index ? -1 : index)} > {open == index ? ( <KeyboardArrowUpIcon /> ) : ( <KeyboardArrowDownIcon /> )} </IconButton> </TableCell> <TableCell component="th" scope="row"> {index.title} </TableCell> <TableCell component="th" scope="row"> {new Date( index.createdDate.seconds * 1000 ).toDateString()} </TableCell> <TableCell colSpan={6}> <Collapse in={open == index} timeout="auto" unmountOnExit> {index.text} </Collapse> </TableCell> </TableRow> ))} </TableBody> </Table>
