Changing custom fields depending on previous fields

The CMS Questions
1

I would like to have a dynamic customfield the content of which changes depending on the option selected in the previous field.

Specifically I have a customfield called Press Type with three options: a) interview b)podcast c)review and a second customfield called Press Source but I want the options available here to be different depending on the choice of Press Type.

Thank you
