Is there a way to populate checkboxes component (or different component which allows multiple choice) with dynamic values (just like you can do for a dynamic dropdown)? Let's say I want do populate checkboxes with countries. Example form: https://demo.orbeon.com/demo/fr/orbeon/builder/edit/73aeafa983d00f305fb381d72e59ce7c69e2b1ea
Yes, you can do this with Actions & Services:
And note that Actions & Services are a PE feature.
