@kirant33 To make the first record in the timeline layout auto-expand by default when sourcing data from a data page list type, you can use a combination of dynamic UI settings and an activity or data transform. First, identify the property or flag in your data source that determines the "expanded" state. During the data load process (in the data transform or activity), set this property for the first record in the list to mark it as expanded (e.g., ExpandFlag=true). Then, in the timeline layout, configure the visibility condition or expand-collapse behavior to read this flag and auto-expand the corresponding record. Ensure that this logic is applied only when the timeline is initially loaded and not during user interactions. Test the implementation to confirm the first record expands automatically without manual clicks.
