Not sure why there are spaces in some random places 😄

There seems to be a few comments from Johan that are not answered yet.

After fixing them, I’d suggest that you squash all the fixup commits, and then split the PR into to few meaningful PRs that can be reviewed and merged separately. This makes the work less scary for the reviewers.

For example, you can have one PR for enabling search, with a couple of examples.
Next PR could be for enabling lazy loading + examples.
Another PR can be about adding nested menus.

Which one you put up first for review is up to you. You know better how things are connected. Just keep in mind that the repo should be able to run or be deployed free of bugs or problems, after each commit that you add.

This PR have been through a lot and it looks like it's huge when looking at the comments.
That was a review from the public API/interfaces of the branch, So I will close this and create a separate one for the actual code.
