Adding a description field

I can see that Schedule has a data.memo attribute, but how can I get those details to appear in the popup template?

@jp26jp Did you mean the raw attribute? It's an arbitrary property that users can handle by themselves.
What you saw was just a kind of example.
If you want to use the raw property on the template, I think the popupDetailBody template might be useful. (Check the Javascript tab in this page) or You need to implement your own popup and use it through the clickSchedule event.
