You can use the third-party service, Wufoo, to create a customized form for your site.
Note: To receive troubleshooting support for form issues, we suggest using the Form Block, a built-in way to create customizable forms. Wufoo is an alternative for forms that require an option to upload files or images.
The steps in this guide include adding advanced code to a Code Block. This is a Premium feature available in Business and Commerce plans.
Step 1 - Create a Wufoo form
Create a form in your Wufoo account.
Note: File storage is only allowed on paid Wufoo accounts. To learn more, visit Wufoo’s pricing page.
Step 2 - Create the Wufoo code
In the Wufoo Form Manager, click Share in the menu for the form you want to embed.
Scroll down to Advanced Sharing Methods and copy the iframe Embed Code.
Step 3 - Add the Wufoo code
For more detailed steps, visit Adding blocks with Insert Points.
Paste the Wufoo code into the Code box. Click Apply.
Note: This third-party customization falls outside the scope of our support. This means that we’re unable to help further with setup or troubleshooting. Additionally, since this is a code-based solution, we can’t guarantee its functionality or full compatibility with Squarespace. This includes how it functions with our responsive design, particularly its appearance on mobile devices, and if it functions on all templates. Third-party customizations can also cause display issues with future updates to our platform. While we can't help further, there are many resources that can point you in the right direction:
