enhancement for the menu plugin

May be all properties can be added, but at least I would like to see the choice of the nav style (e.g. navbar)

Currently there is no option for that:

This will probably cause problems as soon as you have more than max. 2 levels by default. See #296...

what would be an easy way to get e.g. pills from a Content menue?

Maybe just override tableOfContentsView.html.twig and add the desired bs class.

at on page Pills at another one Tabs? That is not possible I guess.

{% set currentSlug = app.request.query.get('slug', '') %}
<ul class="...{% if currentSlug == 'my-page' %} my-pills{% else if currentSlug == 'other-page' %} my-tabs{% endif %}">
...
