This is not an issue but a request. Apologize for me posting this here.

First of all, thanks a bunch for sharing such an awesome foundational framework and believing in open source.

To clarify, imagine this as the hierarchy for the links on the navigation sidebar:

Page 1

Subpage 1
Subpage 2
Page 2
Page 3

So the above ask is to see the possibility of grouping individual links with a parent/child links, and the the parent bookmark is expandable/collapsable when the child links exist.

I would like to see the possbility of contributing this framework as a developer as well.
