Use recursion and a depth property to remove Item and simply nest Groups

[acstll]

The options object would be something like

var options = {
  loop: true,
  0: {
    loop: false,
    beep: 'boop'
  }
};

where 0 is the depth of the Group.

• new options signature
• The depth prop should be passed as second argument to childrenToArray(el, depth)
• Event names would change
• moveDeep(steps, depth) would need a depth argument passed in
