API Reference > imodeljs-common > DisplayStyles > RenderSchedule > RenderSchedule.ElementTimelineProps > elementIds elementIds elementIds: string | string[] The Ids of the elements to which this timeline applies. note Prefer the compressed representation - lists of element Ids can be comparatively enormous. note For a DisplayStyleSettingsProps associated with a DisplayStyleState obtained via IModelConnection.Views.load, this property will be an empty CompressedId64Set. They are omitted to conserve bandwidth and memory because they are not needed for display on the frontend. Defined in core/common/src/RenderSchedule.ts Line 136 Last Updated: 12 June, 2024
