Feature Request: Highlight current region in sidebar

[octref]

This is a great feature I miss from gitbook. It's also on vuejs.org.

Example: try to scroll in this page: https://vue-loader.vuejs.org/guide/pre-processors.html. No updates on sidebar.

I'd love to grab this one 😄.

Do you have any suggestions for where this should live? I was thinking about using a scroll event in Layout.vue to change the active class. It would be similar to the approach that vuejs.org uses.

@ryanriv yeah, it can probably live in Layout.vue. Although don't use direct DOM manipulation - you just need to update the hash and the classes will update automatically.

It would be better to add throttle control for the scroll event.

Thanks for the great suggestions! I have some initial work done on this here #272
