Instead, use SurveyJS UI components to generate and style dynamic JSON-based forms of any complexity, right in your JavaScript application — no need for manual coding. The libraries use JSON objects for both form metadata and results, and support seamless integration with any backend system. Render your custom forms, collect responses, and stay fully in control of your data. The JSON form builder component offers a user-friendly drag-and-drop interface, GUI for form branching, and an integrated CSS theme editor for customizing form design.
