There’s a myth going around in the forum that Webflow only allows for 1 product type template.
In that case, if you’d like to sell two different types of products ( not just variants of a product ) you’d have to put all the product variables of all products into the Product Info in Webflow E-Commerce. So let’s say you’re selling watermelons and socks - The attributes of both product A) Watermelon 
: Weight, roundness, tastiness and B) the socks: 
Size, color, pattern would have to be inserted.
To make it even messier, the product page template itself is also limited to one, meaning a sack of conditional if-statements are needed to make it look more or less normal.
as @gdewey said ‘I was all happy designing my fist website in webflow until I found out that the most flexible online visual designer I have ever use has only one template for product page.’
As far as I understand, this is the only solution to selling multiple products. Are there other ways?
