In the data structure, you can set up types to categorise your data. You can link these types to each other and define per type what data should be displayed in the app by means of sections.
An example can be found below:
The type name is Session, this is displayed in the title bar.
The Info is set to visible, with the name Session information and as a Preview. This is displayed right below the title.
The session has Presentations nested under them
The sections Chairs and Topics have data and are visible.
The section Slides PDF doesn't have data, so it's not shown.
The default template comes with a basic data structure, that you can tweak if you like. If you create your own template export from an existing event, the structure of that event is included.
