To build dynamic forms with JSON schema, you define field types and conditional visibility rules declaratively. The form engine renders these schemas and automatically adapts the UI to display or hide fields based on user input.

You can add custom validation rules to a dynamic form by implementing JavaScript expressions. The form engine evaluates these expressions programmatically to enforce complex logic and automated actions during user input.

Yes, you can populate form dropdown choices from an external API. The form engine supports integration with external data sources, allowing fields to dynamically fetch and display choices via API calls during form rendering.

The best way to manage conditional visibility in complex forms is through declarative JSON schema construction. You define conditions based on user input, and the form engine automatically handles the rendering and behavior of conditional fields and pages.

Yes, the form engine supports programmatic manipulation through a JavaScript API. This allows developers to dynamically control form rendering, trigger event-driven actions, and integrate external data sources beyond declarative schema configuration.
