Dropdown without JavaScript

[iBobik]

We would like to have navigation working even in cases when JS does work. For navigation we need some dropdown component, but this one does not work without JS enabled.

It is possible to code dropdown by just focus-within CSS pseudoclass:

It is ok to use JS for less important features.
