LAYOUT_ON_PRODUCT_PAGE

On the Essential version, on the insertion product, I found that: LAYOUT_ON_PRODUCT_PAGE.
There is not translation and even there is help about it.
What is this?

Hi,

With HikaShop 1.5.6, it is possible to choose a product layout for a category or a product.
You can duplicate some product layouts (when you edit the view) in order to have specific display.
Translation is : "Layout on product page"

Regards,
