Why are checkboxes cleared when clicked?

Question

Yii

It is necessary to arrange filtering on the site beautifully.
Filtering itself works, but .. only within native ActiveForm tags.
I do select or checkboxList - everything works wonderfully and multi-select without reloading the page, only the view of this is terrible.
And if I make a layout of a drop-down list with checkboxes in divs, and just checkboxes in a row - the choice occurs only on the last click + the checkbox "resets" the checked checkbox
of the View:

<?php
$this->registerJs(
    '$("document").ready(function(){
        $(document).on("change", "label", function(e) {
        e.preventDefault();
            $("#filter-form").submit();
        });
    });'
);
?>

<div class="shop-new col-md-12 animated bounceInLeft">

<h1>
    New
</h1>

    <div class="col-md-12 filters-menu-section">

    </div>

<?php Pjax::begin([
    'id' => 'productList',
    'enablePushState' => false,
    'enableReplaceState' => false,
]); ?>

    <?php $form = ActiveForm::begin([
        'id' => 'filter-form',
        'action' => ['new'],
        'method' => 'get',
        'options' => ['data-pjax' => true],
    ]); ?>

    <div class="new-sortFilter-nav status_chk">
        <?php echo $this->render('_search', ['model' => $searchModel]); ?>
    </div>
    <?php ActiveForm::end(); ?>

<?= $this->render('_loop', ['dataProvider' => $dataProvider, 'searchModel' => $searchModel]); ?>

<?php Pjax::end(); ?>

</div>

_search.php

<div class="product-search">

    <?php $form = ActiveForm::begin([
        'id' => 'filter-form',
        'action' => 'search',
        'method' => 'get',
    ]); ?>

    <?= $form->field($model, 'category_id')->checkboxList(Category::find()->select(['title', 'id'])->indexBy('id')->column()) ?>

    <?php // echo $form->field($model, 'price') ?>

    <?php // echo $form->field($model, 'new') ?>

    <?php // echo $form->field($model, 'hit') ?>

    <?php // echo $form->field($model, 'sale') ?>

    <?php ActiveForm::end(); ?>

</div>

Or at least how, in this situation, can parent categories be distinguished by a separate class?

Answer 1

Because the data is updated via PJAX, and you do not pass the state of the checkboxes to the model that fills it, so they are reset.
