Option to *not* fill the underlying select

[lianee]

Is your feature request related to a problem? Please describe. Since v11, the underlying select element is filled with the options, even if the options are programmed. While this is not a problem with few options, it can be a huge load on the html page with many elements. Multiply this with a few controls and the page starts to crawl (I have a page with 11 choices and a lot of options that loaded instantly in v10 and now takes 45s to load).

Minimal example using v10 minimal example using v11

Describe the solution you'd like I'd like to have an option to revert to the previous behavior, i.e. not to put the options in the select element.
