Here's what I found: The SQL Lab schema/table sidebar was redesigned as part of [SIP-111](https://github.com/apache/superset/issues/26395), introduced in [PR #37298](https://github.com/apache/superset/pull/37298) (merged January 2026). This replaced the classic dropdown-based `TableSelector` with a new **treeview** (`TableExploreTree`) built on `react-arborist`, which shows schemas and tables in a hierarchical tree. The PR description mentions a **segmented UI** that lets users switch to the traditional select-dropdown method *within* the new panel — but this is a UX affordance inside the treeview, not a way to fully restore the old sidebar [[1]](https://github.com/apache/superset/pull/37298). **There is no feature flag or configuration option** to toggle back to the old SQL Lab sidebar UI in v6. The treeview replacement was designed as a full UI change, not a togglable option. The treeview has received several follow-up fixes addressing usability concerns — [PR #39173](https://github.com/apache/superset/pull/39173) fixed schema filtering, pin/unpin UX, copy actions, and toolbar styling, while [PR #39396](https://github.com/apache/superset/pull/39396) added schema pinning, column sorting, and table schema refresh. So the v6 experience is actively improving. If preserving the old look and feel is important for your end-consumers, your practical options are: 1. **Stay on v5** until your users are ready for the UI change. 2. **Customize the frontend** — the left bar component is well-isolated in `SqlEditorLeftBar/index.tsx` [[2]](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset-frontend/src/SqlLab/components/SqlEditorLeftBar/index.tsx), so a fork or patch to swap back to the old selector is technically scoped to that file. 3. **Watch for upstream improvements** — the follow-up PRs above are smoothing out rough edges in the new tree UI. Would you like more detail on the specific component files involved in case you want to evaluate a frontend customization? <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](<https://go.dosu.dev/dosubot?utm_source=github&utm_medium=bot-comment&utm_campaign=github-comment-footer-20260415&utm_content=reply-with-mention&utm_term=apache%2Fsuperset>).* --- Share context across your team and agents.
