Click option in select and open other fields - AngularJS

JavaScript

I managed to do but I have a little problem

Select Regime → option “Tributação Normal”
Select Situação Tributaria → option “00 - Tributada Integralmente”

After click option “00 - Tributada Integralmente” display:

content ICMS
Select Modalid. de Determ. da BC ICMS
input Alíquota do ICMS

When I click to change option select “Regime” should disappear the contents of ICMS, but does not disappear
