My client is asking for functionality where you could gather products and then print out a pdf with only those gathered products. Similar to this system, see this link: http://www.lapetek.fi/index.php?module=ekauppa&type=2&product=101609
in every product there is a button "Lisää omaan esitteeseen" where you can add the product to basket bit like in shopping cart, then on the right side there is MyLaptek light blue square where you can see the products added and save a pdf to your computer as a brochure. It looks like pdf is partly premade and then data is gathered to placeholders or something.
Is there any way to do this kind of functionality at the moment with some external plugin / custom code?
