Hi,
But that seems to allow me to only add product thumbnails which click through to the full product listing
No, it can also allow you to add the product name, the add to cart button and the description.
For the add to cart button, it can only add it if the product has no variants / options since it can't display variants / options elsewhere than on the product details page.
It also didn't give me access to all my products.
That should not be the case.
So I am looking for a way to embed an entire product listing, short-circuiting the need to have the the thumbnail. (There are also SEO concerns.) This is exactly how we embed forms and modules and video and sliders etc.
If you need to embed a whole listing of products, then it's indeed better to go through a module. First, create a HikaShop content module via the Joomla modules manager, and then you can use that module in your builder.
Is it still the best answer?
If you want to embed on product details page elsewhere, the "component anywhere" extension is still what I would recommend, yes. Note however that this extension is not available on Joomla 4. Since you're on Joomla 3, it shouldn't matter in the short term. But for the long term, you would have to ask the joomla community if there is an alternative to this extension out there.
