🧩 Advanced Dynamic Form Builder with Validation Engine 📝 Updated Description Build a fully-featured, drag-and-drop Dynamic Form Builder in React where users can visually create forms, define custom validation rules, and preview and test the forms in real-time. Generated forms are stored as a JSON schema with both structure and validation rules. Use React DnD for drag-and-drop UI, zod for schema-based validation, and react-hook-form for performant form state handling. All data is saved to localStorage, ensuring privacy and offline usability.

✅ Core Features Drag-and-drop UI using React DnD to add/remove/reorder fields like:

Text input

Email

Number

Select

Radio

Checkbox

Date & time pickers

Dynamic JSON schema generation for both:

Form structure

Validation logic (required, min/max, regex, etc.)

Live Preview Mode to test the form instantly

Real-time validation with zod + react-hook-form

Local persistence of form templates using localStorage

🚀 Advanced Features to Add Here are free and advanced features you can add:

1. Conditional Fields Logic Show/hide fields based on values of other fields (e.g., "If age > 18, show 'Occupation'").

Use zod refinement logic or custom watch with react-hook-form.

2. Reusable Field Templates / Snippets Let users save a group of fields as reusable templates/snippets.

Store in localStorage or IndexedDB for re-use in future forms.

3. Multi-Step / Wizard Forms Break long forms into multi-step flows.

Include step-based validation and progress tracker UI (built with shadcn/ui components).

4. Nested Grouping of Fields Allow grouping fields (e.g., address block with street, city, pincode).

Dynamically render nested zod.object() structures.

5. Form Versioning Let users save versions of the same form and roll back changes.

Use timestamped keys in localStorage or IndexedDB.

6. Live Code Preview (Schema to Code) Show a live code block of the current schema (as JSON or JSX).

Bonus: Let user export the form schema as:

.json

.tsx React component using react-hook-form & zod

7. Custom Components Builder Let users define their own custom component type using input + preview + validation logic.

Add a configuration layer that saves these for future drag-n-drop use.

8. Accessibility & Keyboard Navigation Auto-generate accessible forms with proper ARIA roles.

Keyboard shortcuts for drag/drop or adding fields.

9. Theme/Style Configurator Allow users to customize styling using Tailwind classes.

Add a sidebar UI where users pick spacing, colors, typography (and apply via className).

10. Import/Export Functionality Users can export entire form schemas as .json files and import them again.
