Add two Select two that their values depend on each other

I need to create an Attribute Province and another Municipality. The idea is that when selecting Province 1, in Municipality only the options 1.1 and 1.2 are loaded, in case of selecting Province 2, in Municipality only the options 2.1 and 2.2 should be shown, how can I achieve this?
