Product Options is an Add-On. If you don't see them when viewing the product details you can install the Add-on.
You can give customers the option to add gift wrapping, a gift message or other non-inventoried options to a product they order by adding "extra options" to the product.
You can select different types of fields for the product options. Here is a list of the field types:
For an option with multiple options, such as gift wrapping, select Selection Box under Allow Customer To Enter Option From.
Click on the Add attribute button to add an option. Enter the option name under Option Attribute and if there is an additional cost, enter it under Additional Price.
Select the default option by entering the option name under Default.
It is a good idea to have the option for no option (i.e. No Gift Wrapping) at the default.
To display a field to enter text, select Text Field under Allow Customer To Enter Option From.
If you want to limit the number of characters that the customer can enter into the text field, click on Add attribute and under Option Attribute enter LENGTH. Then enter the maximum number of characters under Attribute Value.
Use this option to allow customers to only enter whole numbers into the field. Select Integer Field under Allow Customer To Enter Option From.
Use this option if you want the customer to enter a decimal number. Select Decimal Field under Allow Customer To Enter Option From.
