Frequently asked questions

How do I fill a checkbox?

Use true, yes, on or 1 to check it. Any other value clears it.

What if a field name does not exist?

That pair is skipped without an error, so check the names if a field stays empty.

Can I edit the fields afterwards?

No. The form is flattened, so the fields are no longer editable in the result.
