Forms Designer Forum

Could you please add to your instructions for pre-filling form fields how to do so for cross-site lookup fields (ie., get, set, and on-change). Would like to be able to do this for a lookup to a large list.

Hello Jeff,

Thank you for your question.

Currently you can use value method to set or get ID of the selected item, handle change event and make field read-only with readonly method. But we will improve support of Cross-site Lookup Column and publish documentation soon. I will put the link in this thread.

We have updated our article with additional samples of working with Cross-site Lookup via JavaScript:
