Conditional logic

Feature Idea (one per thread):

I use Prismic to make websites for clients and I would really like it if things only showed based on the value of another field. e.g. User selects country from a select box and if they select USA it then asks for state but that only displays based on the previous answer.

Issue that it solves:

Better usability for end users.

Hi Roy,

Can you give us more details on what exactly your idea is here?

Is this something on your website or in Prismic? Is this a dynamic form interface?

Any more information you can give us to imagine this feature will really help, like sketches, etc.
