Show product listing as Homepage

Hi, my name is Denise. I just started looking into litecart and would like to change the homepage to just show a listing of all products either all categories incl. subcategories merged together or one particular category. Is there a setting in the admin backend that I am overlooking? 
In what file can I change what will be served for the content section of a page?

This requires LiteCart to crawl through all subcategories before fetching all the products and there is no current feature like that. You would have to rewrite func_catalog and the method catalog_products_query to grab all products of the category id and all subcategory ids. These are not known so crawling is necessary first.

Thank you for replying and replying fast. Is e.g. the "Green Duck" under the Subcategory just a reference to the "Green Duck" under the main category Rubber Ducks (they have the same product code RD002)? Couldn't the visit of the homepage trigger a show category, like when clicking on a category link (kind of called from the template without modifying anything outside the template)?

 Rubber Ducks

      Green Duck
      Yellow Duck
 Green Duck
 Purple Duck
 Red Duck
 Yellow Duck

You can mount a product inside multiple categories. I think that is what you are refering to.

I'm not sure what you mean. Do you want the first page (home) to be an alias for a category page e.g. /category?category_id=1 ?

The alias could serve as a temporary solution. If I may talk about Prestashop from which I would actually like to escape for the small project I am working on right now - as example what I am looking for, there are ways in Prestashop: e.g. through the Featured Products on the Homepage module or a modification like described in this tutorial "Category page as "homepage" of your store" https://mypresta.eu/en/art/developer/category-page-as-landing-page-of-your-prestashop.html maybe something similar like the small modification could be easily done in litecart.

Here is my add-on for featured products https://www.litecart.net/addons/72/featured-products

If you want to redo your index page just create a custom box and include it in includes/templates/mytemplate.catalog/views/index.inc.php.

Deleted my post with a question - I will have a look at the problem again tomorrow, maybe I will figure it out a bit further myself.

When including the box straight in the view file there is no need to store it as a snippet. So step 3 is redundant.

includes/boxes/box_category_products.inc.php does not output any HTML so therefore it needs a view file for stitching the snippets with.

OK, I have to go through it again and see.

Thank you, this worked.

Why not just modify the "views/index.inc.php" ?

Kill the content and add search box reference thru or category list there ?

Hello, I'm also trying to get products on the home page, for example, from category 4, how do I do it?

@vladislaw You could clone one of the boxes on the main page and change the query to fetch a category.

  'categories' => [4, 5, 6],
  'limit' => 10,
]);```
