How to change each html table row accordian

Question

I want to create a dynamic table which gets its all its entries coming from database. I know how to make a simple table accordian by this Twitter Bootstrap Use collapse.js on table cells [Almost Done] . If I apply that technique it turns table rows into accordian but no matter which row i click it only expands first row. Here is the code of my table getting data from database.

<div class="container">
<h2>All the Suggestions of HR</h2>
<div class="table-responsive">
    <table id="myTable" width="100%" class="table table-striped display responsive nowrap table-hover">
        <thead>
            <tr>
                <th scope="col">Status</th>
                <th scope="col">Date</th>
                <th scope="col">Time</th>
                <th scope="col">Subject</th>
                <th scope="col">Message</th>
                <th scope="col">department</th>
                <th scope="col">Actions</th>
            </tr>
        </thead>
        <tbody>
            <?php 
            $sql = "SELECT * FROM hr;";
            $result  = mysqli_query($conn , $sql);
            $nr = mysqli_num_rows($result);

            while($row = mysqli_fetch_assoc($result)) :
            $id = $row['hr_id'];
             ?>


                <tr>
                    <?php $timestamp = $row['timeSent'];
                    $date = date('d-m-Y',strtotime($timestamp));
                    $time = date('H:i:s',strtotime($timestamp));
                    $status = $row['isAnswered'];
                    ?>
                    <td><?php if ($status == 'true') {
                        echo "Answerd";
                    }
                    else{
                        echo "Pending";
                    } ?></td>
                    <td><?php echo $date;?></td>
                    <td><?php echo $time;?></td>
                    <td><?php echo $row['subject'];?></td>
                    <td><?php echo $row['message'];?></td>
                    <td><?php 
                    $cat =  $row['category_id'];
                    if($cat == 1){
                        echo "Suggestion";
                    }
                    elseif ($cat == 2) {
                        echo "Claim";
                    }
                    else{
                        echo "Help";
                    }?></td>   
                </tr>
            <?php endwhile; ?>
        </tbody>
    </table>
</div>
