Help writing a rule to allow only one node in config mode?

Hi All!

In config mode we want to permit only one cli, I have seen examples where you selectively deny. I want to selectively allow here, how I did was to deny the “/” then allow one of the element under / i.e "/allownode. Apparently all sub option under allownode are not being shown at all…
