This is the documentation for ConfiForms Server/Data Center app
However, this might also work for ConfiForms cloud and in most cases it does. But please see this page to understand the differences between server and cloud versions of the ConfiForms app.
This tutorial helps you to understand how to use Insight objects in ConfiForms, how to access the data these objects have and how to make a dependent fields (where the choice in one field results in the reduced umber of options available in another field)
