Conditional dropdown lists

Hello here!

We want to connect a (new custom) field “Country” with a field “Tel. code”. For example, when user selects “Italy” as contact’s country, we expect system to automatically select the “+39” tel. code from a dropdown list. How could we implement this functionality?

To create a parent dropdown list (Country) and then a dynamic one (Tel. code) is not what we are looking for because there is not the desired selection criterion described above.

Thank you in advance for your support. Waiting for your answer.
