How it works

Custom fields features

UI and logic with JavaScript

Add your own field UI and logic with a simple implementation that uses a JavaScript function with internal methods to store information, load external scripts or validate data.

Backend validations with JSON schema

Use the JSON schema standard to add backend validations to your custom fields. This adds a layer of security to validate field data structure: length of an array, object properties, string formats, etc.

Style your custom field with CSS

We have generic CSS classes and variables you can add to your source code to adapt your field style to the rest of your form. If you need further customization, you can always add your own CSS rules in our settings.
