I have customized a Layered navigation modules in Magento 2. However, I can't write a controller to get all content of category page and load into controller page(localhost/magento2/layerednavigation/index/index/id/17?cat=15&style_general=117).

The controller page will load but it don't filler product. I have checked and seen that controller page don't get param(cat, style_general....). Summary, I want write controller to load category page. However, I am facing the issue is the filler don't work into controller page.

Please refer code: 1. Code for layout: layerednavigation_index_index.xml

All you need to do is get category id from url and set in registery and use it in block,
This is what controller execute contains:

$catId = (int)$this->getRequest()->getParam('id', false);
$this->_coreRegistry->register('catid', $catId);

Here is the block function where you can access your registery category id and using it just fetch all categories :

Initialization:

       protected $_coreRegistry;
       private $_itemCollectionFactory;

Constructor :

public function __construct(
    ...
    \Magento\Catalog\Model\ResourceModel\Category\CollectionFactory $categoriesCollection,
    \Magento\Framework\Registry $coreRegistry,
    ...
) {
    ...
    $this->_itemCollectionFactory = $categoriesCollection;
    $this->_coreRegistry = $coreRegistry;
    ...
}

And here is the function to get category list:

public function getCategoriesList()
{
    $cid = $this->_coreRegistry->registry('catid');

    $categoryFactory = $this->_itemCollectionFactory->create()
                            ->addAttributeToSelect('*');

    return $categoryFactory;
}
