Add Navigation module compatibility

Toolbar is a core feature.

Navigation bar is a Core Module and is default in v11 as I know. It is experimental in 10.3, but honestly it works sooo great - there is no need wait and not using it. This is a massive usability step forward - i install it on every site. No issues yet except Workbench.

Still marked as experimental in 11.x

I'd be happy to review an MR though.

I will also note that I reviewed the module and it has no API and no clear means for adding items.

I would wait until it is stable and those are provided, as they are in Toolbar now.

From my understanding this is just core menu api. Add the menu items and routes and we are done… not that complicated.

I was able to get the menus added to the Navigation. See attached patch.

This patch doesn't take into account sites still using Toolbar but I wasn't sure how to keep both concurrently (Do I just duplicate all and rename?). Any advice on that would be helpful.

We might have to use dynamic routing to support both. See https://www.drupal.org/docs/drupal-apis/routing-system/providing-dynamic... → . With that approach, we could dynamically set the path based on whether Toolbar or Navigation were installed.

I still don't quite understand if Navigation will ever get past its "Experimental" status, especially given https://www.thedroptimes.com/49399/drupal-core-adopt-gin-admin-theme-rep...

It looks like we can use hook_menu_links_discovered_alter()

See ✨ Support the gin theme Active for an example.
