You can offer additional options related to an Item beyond quantity/inclusion. Examples include colour, size, material, etc. These selections can modify the price of the base Item, which is discussed below
Multiple options may be added, and within each option, multiple available values. When there are more than 6 available values, they will be displayed in a drop-down box instead of a list, unless the Allow Multiple Selections option is enabled, in which case a list of checkboxes is displayed.
The amount for the available values can be either: (a) flat price, (b) % of the base price, or (c) % of the base price + previously selected options.
When there are multiple options, they can be sorted by dragging and dropping.
