For compact, but complete, coverage of how to configure each input type the best resource is the schema docs https://zapier.github.io/zapier-platform-schema/build/schema.html#fieldschema

The Examples and Anti-Examples show which combinations are allowed and disallowed by the Zap Editor.  

If you (or anyone else reading) have thoughts on how, if we did a total rewrite, we could best present that content clearly please share.  Which docs do you have to cross reference to get the job done?  How much understanding of how the Zap Editor works are we forcing you to come in with?  We’re investing in our developer content this year and want to hear about we can create an ideal learning and reference experience.
