Interactive Legend allows users to filter layers in the map by changing the visibility of features based on categories and ranges in the legend. This allows users to explore the map holistically or to focus on the categories that are most relevant to them. Choose from paired feature-specific effects, such as bloom and blur, to distinguish between selected items in the legend and the remaining data. Choose from several muted options to emphasize selected items in the legend while other items remain on the map in muted colors. You can include the screenshot tool to allow users to capture images of the map. (To learn more, see the blog article about using Interactive Legend.)
