Cascading Prompts

In this topic we will be talking about Cascading Prompts.

Imagine the end user wants to see some information about flights from a specific airport, but she wants to look for this airport using the Geographic hierarchy. So, she first wants to select the Country the airport is in, then the City in this country, and lastly, the specific Airport.

This is exactly what the Workflow below does.

There are lots of other possible examples of these kind of prompts, like time (year - quarter - month - day), product hierarchies, etc.

It may look a bit complicated, but if you look closer there is a group of Nodes (ending with a Single Selection Widget) that repeats for each level in the hierarchy we want to cascade through.

And, the block marked with 'Output' is just that: generate the output the user wants to see now she found the Airport she was looking for.

I have posted the entire 'selection' part on my community Hub if you are curious...
