Wondering which website frameworks/CMS/addons are #GDPR #cookie compatible and actually wait for "ok" click to set cookie.

Anybody know of any comprehensive list of tests and comparision?

E.g. Stuff like #wordpress, #strikingly, etc.

And what about external JS that sets its own cookies (livevchats, google ads, etc). Do they wait until the website's own "ok to cookies" Button has been clicked?

Is there a kind of common JS Api / flag that is honored? Or chaos for every website owner?
