Hi, The properties that can exist in a timeline are dependent on the template you are using. You can also add your own properties to existing templates. To see what properties the template you are using has, you can open Timeline Settings (the cog icon), and click the item "Properties". This will expand to show you the properties the template has, and what type they are (eg. number, text etc.) You can also add new ones here by clicking the green plus sign. You can read about Timeline Settings here: https://help.aeontimeline.com/article/67-timeline-settings Let us know if you need more help. Jess
