If you are using configurable options, the module will automatically discover these fields and let you select which options are valid for the server.
With this feature, you can specify exactly the valid options for the server. Only servers matching the order details will be assigned.
If a server is valid for all configurable options, you can choose the option "ALL_OPTIONS".
The option ALL_OPTIONS is automatically added to the drop-down menu; you do not have to create this option in your configurable options group.
