Custom code works on all paid plans (except for the archived Creator plan). With a Free plan, you can see working code in Preview mode but not in a published project.
With Google Forms, you can create custom forms and surveys. To embed them in your Readymag project, please follow these steps:
- Sign in to your Google account, go to Google Forms, and create a form.
- On the upper-right corner, click Send → Embed HTML and copy the code.
- Open your Readymag project and add the Code widget. Paste the code from Google Forms into the Widget code section and click 'Save & Close'.
To learn more, please refer to the official Google Forms documentation.
