Después de mucho pensar, he creado una lógica que se adapta perfectamente a mis necesidades. Los datos se distribuyen en el acordeón correctamente. Pero los paneles de acordeón no están colapsados por defecto. Estoy haciendo una nueva pregunta para eso. Aquí está el Enlace
<?php
$fistForLoopEnds = false;
$secondForLoopEnds = false;
$thirdForLoopEnds = false;
$fourthForLoopEnds = false;

<?php foreach ($this->data2['distinct'] as $key) { ?>
<div class="panel panel-<?php if ($fistForLoopEnds != true) {
echo "danger";

$accodianId = "collapseOne";
$accordionExpanded = "true";
