PHP Codeigniter foreach崩溃

Question

I want to make this kind of collapse in my php. Here is an example:

 <meta name="viewport" content="width=device-width, initial-scale=1"> <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css"> <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script> <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script> <a data-toggle="collapse" href="#collapse1">Heading</a> <div id="collapse1"> <a data-toggle="collapse" href="#collapse2"> Category </a> </div> <div id="collapse2">Items</div> 

I want to apply something like that, in here:

<?php
$i=1;foreach($itemlist as $value) {
    echo "<h3>Tower Type : ".$value['notower']."</h3><br>";

    foreach($value['items'] as $val) { ?>
      <?= "<h4>".$val['groupem']."</h4><br>"; ?>
      <table class ="table table-bordered table-hovered table-striped table-condensed">
        <thead>
          <th><?= "Item Name" ?></th>
          <th><?= "Value" ?>
        </thead>
        <tbody>
            <?php foreach($val['item'] as $v) :?>
            <tr>
                <td><?= $v['nm_detailem']?></td>
                <td><?= $v['em_value']?></td>
            </tr>
            <?php endforeach;?>
        </tbody>
      </table>
    <?php } ?>

<?php } ?>

How can I do that? I'm stuck at where to put those href .

You could use the following:

$sOutput = '';
foreach ( $aData as $sData){

     If($sOutput != ''){
         $sOutput .= '</div><div class="collapse hidden">';
     }
     $sOutput .= '<a href=""></a>';
}

If(count($sOutput) == 1 && $sOutput !== ''){$sOutput .= '</div>';}

Add to css:

.hidden{display:none;}

Your jQuery could be:

$(".collapse").on('click', function(){
    $('.collapse').addClass('hidden');
    $(this).removeClass('hidden');
});
