Features


SIFA is a powerful JavaScript library designed to simplify the creation of dynamic and interactive forms. With SIFA, you can easily define rules and actions that respond to user input, allowing you to create complex form behaviors without writing extensive code. Whether you're building a simple contact form or a complex multi-step application, SIFA is the tool you need to create engaging and responsive forms with ease.


SIFA includes preset actions for common form interactions, and supports custom actions for unique scenarios. Whether you need to show or hide fields, validate inputs, or trigger complex workflows, SIFA has you covered.

SIFA applies logic to control what's shown and calculated based on user input — without touching your page's layout or styling.

Whether you're building a simple contact form, a multi-step application, or a product configurator, SIFA gives you the tools to create responsive, engaging forms with ease.

SIFA's efficient rule processing and minimal overhead means your forms load fast and respond instantly — delivering a seamless experience for both developers and end users.

Whether you're writing code or prefer a no-code approach, SIFA is intuitive enough for non-developers yet powerful enough for developers who want full control.

Examples


Editor


The SIFA library is configured with a JSON object that is passed as part of the class initialization. The editor allows you to modify this configuration in real-time, providing immediate feedback on how your form will behave.
