🗳️One-time add charge feature

The default setting of the app will make the add charge product's quantity to be as the same as the quantity of the main product. So let's find out how to set the maximum of add charge product to 1.

Go to main page of Shopify admin -> Avis Product Options -> Avis Option. Click on Create Option Set, then add an Option type for extra charges (Radio Button, Drop-down Menu, Color Swatch, and Image Swatch).

Fill in the values that you want to set charges, for example, we have here the sizes with different price point.

In this case, we want the size to count only as 1 regardless of the main product quantity.

Click on "Show advanced Option" -> Tick on "One time add charge"

Choose your desired group of option and hit "Save"
