Did you set already the relationship between them, in their models?

What i would suggest is :

Controller

$shops = Shop::find($shopID);

$products = Shop::find($shopID)->product;

return in your view with($shops and $products)

now the loop in the view

@foreach($shops->categories as $shop)
 
{{ $shop->category_name }}  //or whatever you want to get

@endforeach

@foreach($products as $product)

{{ $product->product_name }}

@endforeach

Yes i set the relationships.

Your idea is going in the right way. But what i need to show is under each category the products, that belong to the category

like:

@foreach($shop->category as $category)

{{ $category->name }}

@foreach($category->products as $products)

{{ $product->name }}

@endforeach

@endforeach

This i do already. But instead of only the product for the shop and the category i get all products to the category, doesn't matter which store it is.
