The advanced option group

Naming an option group advanced will hide it by default from the user unless they enable expert mode.

optionGroups: {
  fit: ["chestEase", "hipsEase", "stretchFactor"],
  style: ["armholeDrop", "backlineBend"],
  advanced: [ "plutoniumCount" ]
} 

The advanced option group can also have nested groups
