The Custom Js and CSS addon enables you to make your forms more functional. The addon is perfect for applying additional functions to the form. This is also perfect for integrating your form with other 3rd party services.
To activate the Add-on:
Go to your Wix Editor page.
Double click on the form to open the Settings.
Here, Move to the Add-ons section.
Open Add-ons.
Add the Custom Js and CSS add-on.
Even with basic coding skills, you can easily set custom codes to the add-on. And if you're a business subscriber, we can also help with customizations tailored specifically to your needs.
