How would i make the gui position non relative to ancestors position

  1. What solutions have you thought of so far?

My code

uis.InputBegan:Connect(function(input, gpe)
    if not gpe and input.UserInputType == Enum.UserInputType.MouseButton1 then
        local pos = uis:GetMouseLocation()
        local guis = plr:WaitForChild("PlayerGui"):GetGuiObjectsAtPosition(pos.X, pos.Y)
        local highest = -math.huge;
        local highestGUI;
        local highestPos;
        for _, v in next, guis do
            if v.ZIndex > highest then
                highest = v.ZIndex
                highestGUI = v
                highestPos = v.Position + v.Size
            end
        end
        repeat
            local pos = uis:GetMouseLocation()
            highestGUI.Position = UDim2.new(0, pos.X, 0, pos.Y)
            game:GetService("RunService").RenderStepped:Wait()
        until not uis:IsMouseButtonPressed(Enum.UserInputType.MouseButton1)
    end
end)
