I am redoing a client site – celias.no and also adding a WooCommerce minimum quantity drop down.

The goal:
Add a drop down with a minimum quantity and maximum quantity.
Begins with 10 then goes 10 steps at a time. 10, 20, 30 all the way up to 500.
Shop page: When clicking “Add to cart” will add the minimum of 10.

Product page: A drop down is available to select the quantity.

The Cart page: Contains a drop down to easily change the quantity.

The code used:
(Add the code to the child theme functions file.)
