Can't display certain categories?

Question

Yii

I can't figure out how to display certain categories. When I go to which category, then all the products from different categories are displayed, as if everything is in a bunch. I can't figure out where to take the $id to pass that selected category, and there, for example, it was possible to filter the product by the category that the user selected.
Previously, site.loc/category/index?id=18
CategoryController was displayed like this before, this was before without model search

public function actionIndex($id)
{
    $query = ProductPit::getProductByStatus($id);
    $countQuery = clone $query;

    $pagination = new Pagination(
        [
            'defaultPageSize' => 21,
            'totalCount' => $countQuery->count(),
            'forcePageParam' => false,
            'pageSizeParam' => false
        ]
    );

    $models = $countQuery
        ->offset($pagination->offset)
        ->limit($pagination->limit)
        ->all();

    if (empty($models)) {
        throw new HttpException(404, 'Категория не найдена');
    }

    return $this->render('index', [
 'models' => $models, 
 'pagination' => $pagination
]);
}

And now I have model search and CategoryController code like this, and I also use listView

public function actionIndex()
{
    $searchModel = new ProductPitSearch();
    $dataProvider = $searchModel->search(Yii::$app->request->queryParams);

    return $this->render('index', [
        'searchModel' => $searchModel,
        'dataProvider' => $dataProvider,
    ]);
}

Actually, as before, you need to pass the id of the selected category to the controller using the address bar, then from the controller pass them to the search model, well, in the search model you need to declare the corresponding property and search for it.
