### SUMMARY At Airbnb, we have a dataset that contains > 10k columns and metrics. Given the size of this dataset, the current rendering of the show all datasource target list is not realistic. To address this issue, this commit introduces virtualized rendering for the field sections, which significantly improves performance and supports handling large-sized metadata datasets. ### BEFORE/AFTER SCREENSHOTS OR ANIMATED GIF Before: https://github.com/apache/superset/assets/1392866/4402d60f-ef57-45d7-aaa6-aacae28507d7 After: https://github.com/apache/superset/assets/1392866/bd463655-0ff0-433a-972a-2d7b6c817c34 ### TESTING INSTRUCTIONS Go to "create a chart" and then - test drag and drop - test show/hide all - test collapse/expand header ### ADDITIONAL INFORMATION <!--- Check any relevant boxes with "x" --> <!--- HINT: Include "Fixes #nnn" if you are fixing an existing issue --> - [ ] Has associated issue: - [ ] Required feature flags: - [ ] Changes UI - [ ] Includes DB Migration (follow approval process in [SIP-59](https://github.com/apache/superset/issues/13351)) - [ ] Migration is atomic, supports rollback & is backwards-compatible - [ ] Confirm DB migration upgrade and downgrade tested - [ ] Runtime estimates and downtime expectations provided - [ ] Introduces new feature or API - [ ] Removes existing feature or API -- This is an automated message from the Apache Git Service.
