Creating Slicers in Custom Insights Dashboards
You can create slicer visualizations on custom Insights Dashboards to filter the data that appears across all other visualizations on the corresponding dashboard tab, including other slicers. As you choose values across multiple slicers, the other slicers and visualizations will be filtered to include only the data that intersects those selected values, allowing you to filter down to just the data that meets the filter criteria you selected in your slicers.
Object-based tables: If you are trying to create visuals and slicers for objects with custom attributes, please reference the To create KPIs/visuals for object-based attributes procedure within the Using Object-Based Attribute Tables for Custom Insights Dashboards article instead.
