Conditional inputs

Is there a way to make the inputs on the meta box conditional on each other?

For example, two dropdowns:

Dropdown -- States: (CA,NY,MO,KC, etc..)
Dropdown -- City: NY -> (NYC, etc..)

The user first select a state, then he/she can select a city from that state.
Or something like

Radio -- Yes/No
Dropdown -- (Option 1, Option 2, Option 3, etc..)

The user first select if he/she wants to add a certain thing, if yes allow to choose what to add.

Thank you,
