If you'd like to use private/internal methods without reflection, this maybe usefull: https://github.com/aelij/IgnoresAccessChecksToGenerator

Maybe unusual, but still possible.

If you need a sample, my adapter here: https://github.com/iobroker-community-adapters/ioBroker.webui/blob/master/dist/backend/main.js is a ESM one

> Thanks. And generally is working correctly with controller just compact mode is not working? Think so. But my adapter does not use many features, but I think it's workin.

 there is a preview... what do you mean?

I‘ve not looked into it due lack of time.

What help do you need?

Not really... I didn't invent it, only converted to typescript and extended it. I'm also always looking on how to do smth.... But I really don't find it to hard.

I would think, the floating would be easier. Because the other one, needs to reposition the other containers ;-) my main point is, keep the elements in DOM, don't remove...
