I am able to SET the attributes within a product (color, size), it just looks like your theme doesn’t allow people to select those options. Unfortunately, this is wacky for a seller…. so there needs to be a way for people to select and choose those options on the front-end. Why that’s missing?
It’s standard in WooCommerce, but doesnt work with Woo+Dokan….???
Customer can select size,color etc if the product is variable. You have to add those attributes in variation and also you can manage different price or stock for each variation. Like- if you have one product with 3 different size then you can put different price and stock for the different size. To add variation for a product you have to change the product type to variable product.
