How to add product options

[kkhys2]

Is there a way to add a line item property to Hydrogen, as in Theme?

For example, we are selling slacks and would like to give the option of raising the length of each line item, but we don't know how to do this.

Self resolved.
I can define custom attributes by adding the attributes property to the AddToCartButton component.
