How to create a field select that depends

Hi guys,

Could someone explain to me if I can create a field select that depends from another select?

For example,

Create a select for province and then city. I want that in registration form the user select first province and then in city that the select shows only the city that belong to that province.

Thanks in advance

It is possible?
