Description

Prerequisites

What theme are you using?

core

Version

5.x

Current Behavior

When the list contains a large number of elements (10000), the interface performance is poor. The result of the input operations or clicking on the list control buttons, you have to wait a few seconds.

Expected Behavior

Operations work without delay.

Steps To Reproduce

  1. Open demo
  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

Direction de recherche
Investigate the performance of rendering large arrays in rjsf. The issue suggests that operations on lists with 10000 elements are slow. Start by profiling the component using browser DevTools to identify bottlenecks. Consider implementing virtualization using libraries like react window or react virtualized to only render visible items. Also look into memoization and avoiding unnecessary re renders. The Codepen demo (https://codepen.io/iron vd/full/qBYMZOj) can be used for testing. The issue is open but has not been worked on; there is no linked PR.
