Your unified custom filter component that combines dropdowns, radio buttons, and checkboxes into a single chart plugin with cross-filtering and Jinja templating support is a clever approach to a common pain point — the layout constraints of the traditional filter bar. A few observations on how this aligns with Superset's architecture: **Plugin Architecture Fit**: Your approach of building this as a custom chart plugin is well-aligned with Superset's modular plugin system. Plugins register via `ChartPlugin` and can declare `Behavior.InteractiveChart` to participate in cross-filtering [[1]](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset-frontend/src/dashboard/util/crossFilters.ts). This means your component can emit `updateDataMask` actions to filter other charts on the dashboard just like native cross-filters do [[2]](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset-frontend/src/dataMask/actions.ts). **Cross-Filtering Integration**: Superset's cross-filtering state is managed through a Redux `dataMask` slice [[3]](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset-frontend/src/dataMask/reducer.ts), and any chart that opts into `Behavior.InteractiveChart` can participate. Your plugin leveraging this for filter-like behavior from anywhere on the canvas is a creative use of the existing infrastructure. **Jinja Templating for Dynamic Dimensions**: The `filter_values()` and `get_filters()` functions in Superset's Jinja context [[4]](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset/jinja_context.py) already make filter state available to SQL queries, enabling the kind of dynamic column/metric swapping you describe. Combined with the `metric()` macro for dynamic metric substitution [[5]](https://github.com/apache/superset/blob/829e4d92d91ceae4b43b1ed3b063ffe45377799c/superset/jinja_context.py#L998-L1040), this provides a solid foundation for parameter-driven analytics. **Gap This Fills**: Currently, there's no native way to place filter controls directly on the dashboard canvas — filters are confined to the dedicated filter bar. Your approach of using a chart plugin to achieve free-form placement is an inventive workaround that addresses a real usability gap. For getting community traction on integrating this into mainline, you might consider opening a formal [SIP (Superset Improvement Proposal)](https://github.com/apache/superset/issues?q=label%3Asip) or a PR with the plugin. The maintainers typically evaluate contributions based on broad applicability, maintainability, and alignment with the existing architecture — and your design seems to check those boxes by working within the plugin and cross-filter systems rather than against them. <!-- 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.
