Here's a roadmap of the key files you'd need to touch: **Where the filter bar currently lives:** The left-side (vertical) filter bar is rendered in [`DashboardBuilder.tsx`](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset-frontend/src/dashboard/components/DashboardBuilder/DashboardBuilder.tsx#L607-L620), not in the grid itself. It uses a `ResizableSidebar` positioned via CSS Grid, separate from the dashboard canvas. The filter bar component lives at `src/dashboard/components/nativeFilters/FilterBar/index.tsx` [[1]](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset-frontend/src/dashboard/components/nativeFilters/FilterBar/index.tsx), with individual filter controls in the [`FilterControls/`](https://github.com/apache/superset/tree/HEAD/superset-frontend/src/dashboard/components/nativeFilters/FilterBar/FilterControls) subdirectory. **To make filters a draggable canvas element (like Header, Divider, Chart), you'd need to modify these areas:** 1. **Add a new component type** in [`src/dashboard/util/componentTypes.ts`](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset-frontend/src/dashboard/util/componentTypes.ts) — e.g. `FILTER_BOX_TYPE = 'FILTER_BOX'` 2. **Create the canvas component** — a new file like `src/dashboard/components/gridComponents/FilterBox.tsx`, modeled after existing components like `Divider.jsx` or `ChartHolder.tsx`. This component would wrap the filter UI (reusing logic from `FilterControl.tsx` in [[2]](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset-frontend/src/dashboard/components/nativeFilters/FilterBar/FilterControls/FilterControl.tsx)) and handle drag/drop + resizing. 3. **Register it** in the [`componentLookup`](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset-frontend/src/dashboard/components/gridComponents/index.js) map in `src/dashboard/components/gridComponents/index.js`. 4. **Add nesting rules** in [`isValidChild.ts`](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset-frontend/src/dashboard/util/componentTypes.ts) to define where your filter element can be placed (e.g., inside `GRID`, `COLUMN`, etc.) [[3]](https://app.dosu.dev/a28d3c7e-a9d3-459e-9fb6-3a6f9ff4f357/documents/95e969a1-5f7d-4ddd-87e0-e3b7b27ae6ab). 5. **Add a palette drag source** in `src/dashboard/components/BuilderComponentPane/` so users can drag the filter element onto the canvas in edit mode [[3]](https://app.dosu.dev/a28d3c7e-a9d3-459e-9fb6-3a6f9ff4f357/documents/95e969a1-5f7d-4ddd-87e0-e3b7b27ae6ab). 6. **Wire up filter state** — your canvas filter component needs to dispatch `updateDataMask` Redux actions and connect to the same `dataMask` state that the native filter bar uses, so filter selections actually propagate to charts. **An alternative approach worth considering:** There's an active [SIP-218](https://github.com/apache/superset/issues/41498) proposing exactly this — canvas-based filter chart plugins that use Superset's existing cross-filtering infrastructure instead of modifying the layout system [[4]](https://github.com/apache/superset/issues/41498#issuecomment-4828050003). The approach builds filters as **chart plugins** with `Behavior.InteractiveChart`, so they emit cross-filter events like any other chart. This avoids creating a new layout component type entirely. You can see a working implementation at [krmmkr's branch](https://github.com/krmmkr/superset/tree/6.1-updates2/superset-frontend/plugins/custom_controls) [[5]](https://github.com/apache/superset/discussions/40822). The chart-plugin approach is simpler to implement since it works within the existing plugin system, but as noted by a maintainer, the long-term direction the community has discussed is letting native filters live directly on the canvas with local scoping [[4]](https://github.com/apache/superset/issues/41498#issuecomment-4828050003). <!-- 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>).* --- Docs are dead.
