  2. Click "react-jsonschema-form DEMO" to go to the sandbox (link is very big for issue text editor...)
  3. Input value in array object
  4. Try to click move down/move up/delete button

Contributor guide

Research direction
Profile the list rendering to identify performance bottlenecks. Consider implementing virtualization using libraries like react window or react virtualized to render only visible items, and memoize components to reduce re renders.
