What it does
This workflow creates a customizable form with a dynamic dropdown field that automatically updates its options from an external data source. How it works - The workflow polls an external data source (Google Sheets in this example) at regular intervals - New values are processed and formatted for the dropdown - The form automatically updates with the new dropdown options Set up steps Configure your data source: - Default setup uses Google Sheets - replace with credentials for your sheet - set up the update frequency - Or modify to use any other data source (API, database, etc.) Adjust the form configuration: - Customize the form title and description - Add or modify form fields as needed - The template includes the dropdown field by default Connect form submissions: - Use the "Execute Workflow" node to process form submissions This template provides a foundation for creating dynamic forms that stay synchronized with your data sources, making it ideal for situations where dropdown options need to reflect current data.
