Don't build on it in production. See [API maturity](https://www.gooddata.ai/docs/gooddata-ui/latest/integrations/platform/api-maturity/index.md). > This transformer ís used to extract break up slide from current section. Break up slide is created from section title and description. This transformer only create slide when section has title or description. **Signature:** ```typescript breakUpSlide: (section: IDashboardLayoutSection) => IDashboardLayoutSection[] | undefined; ``` ### ISectionSlidesTransformerFunction.containerSlide > **Alpha API.** Initial API, highly likely to change outside SemVer. Don't build on it in production. See [API maturity](https://www.gooddata.ai/docs/gooddata-ui/latest/integrations/platform/api-maturity/index.md). > This is more complex transformer that is used to transform container item in the layout to a slide. Container item is transformed as a structured slide, but if it contains a visualization switcher, it is transformed to a flat list of visualizations that are part of container item. **Signature:** ```typescript containerSlide: (item: IDashboardLayoutItem, transform: (section: IDashboardLayoutSection) => IDashboardLayoutSection[] | undefined) => IDashboardLayoutSection[] | undefined; ``` ### ISectionSlidesTransformerFunction.containerSwitcherSlide > **Alpha API.** Initial API, highly likely to change outside SemVer. Don't build on it in production.

First slide will contain first visualizations from both switchers, second slide will contain second visualizations from both switchers and last slide will contain third visualization from the first switcher and empty item from the second switcher. ### ISectionSlidesTransformerFunction.containsVisualisationSwitcher > **Alpha API.** Initial API, highly likely to change outside SemVer.
