Consider there is a product with multiple options, be it in terms of size, colour, material or any other attribute. Now, if a customer adds that product to the cart from the home page or the category page then he doesn’t get to choose between the options. By default the first option of the product is selected.
So for instance, consider a t-shirt which is available in four colours and red is the first one in the list. Now, if a customer adds that product to the cart from the category or the home page, then by default the first option would be selected in the checkout page. To choose between the options he has to go to the product page.
This feature would allow customers to choose between the options when they add any product to the cart.
Thank you for your valuable feedback. This feature request has already been planned and will be implemented in the updates to come in a couple of months.
