Client needs users to add to cart in bulk. I have been searching for apps but only 1 does the job but not at all (https://apps.shopify.com/bulk-products-order) since I need colors and sizing the table of that app would be too big.
Of course the QTY needs to be relative to the product variant. Thanks
Did you find any solution yet? If not, you can check MultiVariants - Bulk Order to order multiple variants in a single click.
You can display your variants in a grid/matrix view with the swatch option.
Here is an example product you can take a look at this sample product Variants Grid/Matrix layout with a swatch (3 Options)
