An Option Set is a collection of multiple options (like size, color, engraving, material, etc.) grouped together to simplify management and assignment.
You can create one Option Set containing all the related options for a specific product or group of products — for example, an “Apparel Options” set might include Size, Color, and Fit Type. Once created, this Option Set can be:
Assigned to a single product or multiple products at once.
Duplicated, so you can easily reuse it for another group of products with minor adjustments.
Note: Each product can be linked to only one Option Set at a time. However, that Option Set can include multiple options within it.
