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 shows you to to use the new feature of ConfiForms app available since version 2.7.0.
"Use proxy" setting is available for
- Dynamic Dropdown (auto-suggest) - Database
- Dynamic Dropdown (auto-suggest) - Webservice
Enabling this option for your field helps you to setup a tunnel / proxy to the underlying service to make the lookups. When the option is enabled, ConfiForms doe snot need to load all the choices in advance, which speeds up the form rendering times dramatically and allows to setup fields that can have millions of choices (as much as the underlying service has to offer)
