Hi Guys!
Each "Programa" has several "Sub-Programa", I would like the user to select a "Programa", only "Sub-Programa" that are linked to it would appear.

In this case, the "Viridian" programa has 3 sub-programa:
Programa 01, Programa 02 and Programa 03
But when I select "Viridian" in the application, all sub-programa would appear... I would like only Programa 01, Programa 02 and Programa03 to appear.

Is it possible to do this?
