imported mindmap file wont compile

I’ve imported a mind map from freeplane. All of the folder structure and notes are importing correctly, but when I try to compile there’s nothing available in the contents section of the compile dialog. All of the documents have a tick in the compile checkbox in the inspector.

hmm, if I check ‘add front matter’ and choose the top level folder in the dropdown, then it all becomes available. Not sure if this is how it’s supposed to work. I assumed add front matter was just for setting the book cover?

Your mindmap has to be moved to inside the draft/manuscript folder.

thanks.
