If you want to keep a Google Forms dropdown aligned with a Google Sheets list but do not want to maintain code, the practical choices are manual paste before launch or a no-code add-on workflow. Google Forms stores its own question choices, so the dropdown does not stay linked to a Sheet range by default.
If you do not want Apps Script, focus on two paths: manual paste for rare updates, or a spreadsheet-backed add-on for repeatable updates from a selected Google Sheets source.
Best when the list changes rarely and one person can safely update the form before launch.
Best when the source list lives in Sheets and you want a setup sidebar, preflight, and a controlled update flow.
Useful when respondents should follow different paths, but it does not dynamically rewrite the next dropdown.
If options represent seats, inventory, or reservations, keep a buffer and do not rely on the dropdown alone.
Google Forms does not natively change the next dropdown based on a previous answer during the same session.
Manual copy/paste may be enough if the list changes once in a while and the team can keep it clean.
Use Sheets as the source of truth and refresh the form question choices before sharing the form widely.
If the form has complex conditional logic, a custom app or a different form builder may fit better.
If the copied form updated correctly, move the same mapping to the real form and the real sheet column. After one successful first run, a short Marketplace review or setup note helps other Google Forms users judge the fit faster.
