Add Responsive Menu with Submenu functionality

[takermaker]

The Problem

first of all the Citizen Skin is amazing, but the current menu is kept very simple, unfortunately there is no function with submenus, it would be great to have the possibility to integrate submenus especially for the mobile view a beautiful Side Menu Bar with Submenus.?

My approach to fix this would be to override or declare all necessary specs in Mediawiki:Common.css page.

PS: I'm planning using this skin as default in my wiki so I'll suffer the same issue.

Ive found a Sidebar Template, i think it will suite the Skin perfectly, its fully responsive, Collapsable and has Multi level menu capability.

It is planned to be worked on but we haven't gotten to it yet.

There are a few considerations that we have to make before moving onto it:

• Different wikis use menus differently, some has shallower menus and some has deeper menus. We have to figure out a way to accommodate the use cases.
• The MediaWiki menu-related components are constantly being worked on. It might take a while to be stable so we are planning to revisit it on the next MW LTS build.
