Conditional value for parameters

[starinfor]

Is it possible to have conditional values ? For example: Suppose JSON has 2 parameters, Country and States. Based on what country is selected, states is populated. Assuming all data takes a server side call.

This has been open for ages, and there's no support for inter-dependent parameters. A related (but not identical) issue is here #256, but I'll close this one as it hasn't had much engagement over the years.

query parameters can be defined by a single schema (which would allow conditional dependencies), but this is not possible for header or path parameters.
