Hi Zhouran

I don't have this in my demo build either - it's probably because it's not part of Adapt 'Core', which is deliberately designed to be as minimal as possible.

The vast majority of additional functionality in Adapt comes in the form of 'plugins' which you have to install and (presumably) configure.

I think this feature should be available as the pageLevelProgress plugin - but it doesn't appear to have been built yet.
