n8n Form with Dynamic Dropdown Sourced from Google Sheets

N8n

Complex Trigger

This n8n workflow is engineered to power an interactive form that features a dynamic dropdown field. It utilizes Google Sheets as the backend data source to automatically populate the options within this dropdown. When the form is accessed or initiated, the workflow executes to retrieve the most current data from a specified Google Sheet. This data is then dynamically used to generate the list of available choices for the dropdown, ensuring that the form always presents up-to-date selections without requiring manual updates to the form definition. The presence of an 'n8n | get wf' node suggests the workflow might also interact with its own definition, possibly to fetch its ID or other metadata essential for the form's construction or dynamic update. This setup is perfect for forms that need frequently refreshed selection options, such as product catalogs, user lists, or project types, directly reflecting changes made in a Google Sheet.
