Can we develop a better drop-down css in TW

This article links to an existing solution to this problem and also a hypothetical future pure CSS solution:

a hypothetical future pure CSS solution

Yeah, this is what I want.
Should we to wait for css to implement that feature natively,
or is it more realistic to wait for someone skilled in .JS to loot one of the described libraries and implement this in TW?
@boris this is allso a project that I would propose for opencollective because it could make the TIddlyWorld more comfortable.
