Creating product options
Add options, like sizes and colors, to your products like this:
1. In Online store settings, click on Catalog and then Products.
2. Select the product page you want to edit by clicking on the product.
3. Go to the Options tab and click on Add New Option to add a product option and related parameters.
4. Add the name of the option (in this example, size) and the input type (here, radio buttons).
5. Click on Add New Value and add all values you want the option to have (in this example, the different sizes are the values). Don't forget to choose a Default value (here, size S).
9. Save the changes and check that the product page looks OK.
I can't see product options?
If you can't see the Options tab on your product pages, check that you have the options setting enabled in your store's Design settings.
