Имеется вывод массива объектов:

<?php $compare = 0; ?>
<?php foreach($arr as $key => $value): ?>
            <?php if($compare != $value['id_storage']): ?>
            <ul class="box box-main box-<?php echo ($value['id_storage']); ?>">
                <div class="box-main-wrapper" style="display: flex; width: 100%;">
                    <li><?php echo ($value['id_storage']); ?></li>
                    <li><?php echo ($value['category_name']); ?></li>
                    <li><?php echo ($value['name_storage']); ?></li>
                    <li><?php echo ($value['mount']); ?></li>
                    <li><?php echo ($value['price']); ?></li>
                    <li><?php echo ($value['exp_date']); ?></li>
                    <li><input type="submit" class="btn btn-primary btn-details" value="Подробнее" style="align-self: center;"></li>
                    <?php  $compare = $value['id_storage']; ?>
                </div>
                <div class="sub-box-wrapper"></div>
            </ul>
            <?php else: ?>
                <ul class="hide box sub-box sub-box-<?php echo ($value['id_storage']); ?>">
                    <li><?php echo ($value['id_storage']); ?></li>
                    <li><?php echo ($value['category_name']); ?></li>
                    <li><?php echo ($value['name_storage']); ?></li>
                    <li><?php echo ($value['mount']); ?></li>
                    <li><?php echo ($value['price']); ?></li>
                    <li><?php echo ($value['exp_date']); ?></li>
                    <li></li>
                </ul>
            <?php endif ?>

При таком выводе в DOM-дереве ul с классом box-main создается первым, а ul с классом sub-box отдельно и ниже, чем ul с классом box-main. Как генерировать ul с классом sub-box внутри box-main, а точнее, внутри sub-box-wrapper ? Первый объект с 'id_storage' записывается в 'box-main', а остальные объекты с таким же 'id_storage' - в 'sub-box'.

Изменяем структуру исходного массива, чтобы можно было его вывести в один проход:

<?php
$formated = [];
foreach ($arr as $item) {
    if (!array_key_exists($item['id_storage'], $formated)) {
        $formated[$item['id_storage']] = $item;
    } else {
       $formated[$item['id_storage']]['compare'][] = $item;
    }
 }
 ?>

А теперь выводим с учетом того, что товары для сравнения у нас помещены в подмассив compare:

<?php foreach($formated as $value): ?>
     <ul class="box box-main box-<?php echo ($value['id_storage']); ?>">
            <div class="box-main-wrapper" style="display: flex; width: 100%;">
                <li><?php echo ($value['id_storage']); ?></li>
                <li><?php echo ($value['category_name']); ?></li>
                <li><?php echo ($value['name_storage']); ?></li>
                <li><?php echo ($value['mount']); ?></li>
                <li><?php echo ($value['price']); ?></li>
                <li><?php echo ($value['exp_date']); ?></li>
                <li><input type="submit" class="btn btn-primary btn-details" value="Подробнее" style="align-self: center;"></li>
            </div>
            <div class="sub-box-wrapper">
             <?php if (array_key_exists('compare', $value)): ?>
                  <?php foreach($value['compare'] as $subitem): ?>
                      <ul class="hide box sub-box sub-box-<?php echo $subitem['id_storage']; ?>">
                            <li><?php echo ($subitem['id_storage']); ?></li>
                            <li><?php echo ($subitem['category_name']); ?></li>
                            <li><?php echo ($subitem['name_storage']); ?></li>
                            <li><?php echo ($subitem['mount']); ?></li>
                            <li><?php echo ($subitem['price']); ?></li>
                            <li><?php echo ($subitem['exp_date']); ?></li>
                            <li></li>
                      </ul>
                  <?php endforeach; ?>
             <?php endif; ?>
            </div>
        </ul>
 <?php endforeach; ?>
