3rd dropdown tier

[Tactica]

I admit I know nothing about dropdown functions. Would like to add a third tier to this code for All, Lookalike, and Recolor as a "check/tick" setting.

function module.Dropdown(module,tier)
	local info;
	if tier == 1 then
		info = UIDropDownMenu_CreateInfo();
		info.text = module.label;
		info.value = module;
		info.colorCode = "\124cFF00FF00";
		info.hasArrow = true;
		info.keepShownOnClick = true;
		info.notCheckable = true;
		UIDropDownMenu_AddButton(info,tier);
	elseif tier == 2 then
		for k,v in ipairs(armor) do
			info = UIDropDownMenu_CreateInfo();
			info.text = v;
			-- info.value = v; -- value equals text if omitted!
			info.notCheckable = true;
			info.func = DropdownTier2;
			info.arg1 = module;
			UIDropDownMenu_AddButton(info,tier);
		end
	end
end

Not sure if you need more code to know whats going on...thanks in advance.
