Selection Map

app:RegisterControl("group.roles", {
  id = "roles",
  type = "multidropdown",
  label = "Roles",
  options = { tank = "Tank", healer = "Healer", damage = "Damage" },
  orderList = { "tank", "healer", "damage" },
  getSelection = function()
    return MyAddonDB.profile.roles or {}
  end,
  setSelection = function(selection)
    MyAddonDB.profile.roles = selection or {}
    MyAddon.RefreshRoles()
  end,
  default = {},
})

Per Option Callbacks

isSelectedFunc = function(value)
  local roles = MyAddonDB.profile.roles
  return roles and roles[value] == true
end

setSelectedFunc = function(value, selected)
  MyAddonDB.profile.roles = MyAddonDB.profile.roles or {}
  MyAddonDB.profile.roles[value] = selected and true or nil
  MyAddon.RefreshRoles()
end

Rules

• Do not rebuild the settings frame from setSelectedFunc.
• Deselect by removing keys or assigning nil.
• Use menuHeight for large option sets.
