The Timeline collection enables you to associate interactive items with specific dates on a chronological scale. Selection of content in the timeline will cause a copy to "pop out", enabling independent manipulation of that content. Like most collections, the Timeline collection can include any asset type, including buttons and even other collections. Buttons in a Timeline can be used to trigger any action, including navigation to other scenes.
NOTE: The Timeline collection is only supported on Windows devices.

- Making sure the asset is still selected in the turn your attention to the Properties panel
- If necessary, assign content to the asset (using the Content field)
- Set a Date to define where the asset will be displayed along the timeline. A double-click in the timeline will also enable you to drag the image to a new date.
