Runtime List

local function getProfileOptions()
  wipe(profileOrder)
  local options = {}
  for name in pairs(MyAddonDB.profiles or {}) do
    options[name] = name
    profileOrder[#profileOrder + 1] = name
  end
  table.sort(profileOrder)
  return options
end

app:RegisterControl("profiles.select", {
  id = "profile",
  key = "profile",
  type = "dropdown",
  label = "Profile",
  listFunc = getProfileOptions,
  optionfunc = function() return profileOrder end,
})

Clearing Dependent Values

When a source list changes, clear invalid dependent selections and notify the row or re-render only after the dropdown interaction is closed.

if not MyAddonDB.profiles[MyAddonDB.profile.selectedProfile] then
  MyAddonDB.profile.selectedProfile = nil
end
