 Hi @Manthan Dave

Thanks for reply.

I mean I want to show all products in default category .

Its layout is equal to a layout in a specific category under Default Category.

I also want to show that products on the root page, e.g. https://hogehoge.com/.

Hello @yuki_ito

Do you want to do it by coding or you can do by admin panel as well. You can assign all products in that category. 

Please let me know if you need any other solutions.

Hi @yuki_ito

Regarding default category , yes you can add all products in default categories as well - You can do it from admin panel and you can also done the same operation using code as well !

Also just to give your more info - Default category is root category of magento , so you need to add your category under the root category only !

Hope it helps

Hello @Manish Mittal

I want to do it by coding to magage code as files.

After, I create /Magento_Cms/layout/default.xml in my theme by coping /vendor/magento/module-catalog/view/frontend/layout/catalog_category_view.xml and saw the root page.

But , in conjecture, its code doesn't specify category, so error displayed as follows.

PHP Fatal error:  Uncaught Error: Call to a member function getDisplayMode() on null in /var/www/html/w_w_auction/vendor/magento/module-catalog/Block/Category/View.php:160

Hi @Manthan Dave

I tried your suggestion.

I can show all products in default categories, but layered navigation with filterable attributes don't work.

I also want to work layered navigation with filterable attributes with not admin panel but using code.

After adding a category under the root category, what shoud I do?
