Feature request - copy data-attr's and/or classes from original select

[MakerTim]

Context

You can hide options via CSS, display: none.
But when using select2 it has no effect.
My request is to add the data-attr's so

In fact, I would suggest two select2 configuration options (defaulted to false if select2 dev wanted backward compatibility) of "copyOptionClasses": true|false and "copyOptionAttributes": true|false which would do exactly that!

More copy data attribute from options, but can be interesting.

Have a way to copy class too (by option)

RE: Can I get a little bit more context on this feature request?

So if an option was defined as such (square instead of angle):
[option class="class" data-something="yes"]
then the corresponding would look like this:
[li class="select2-results__option class" data-something="yes"]

Yes, something like that!

Something that you can share the CSS and display: none them both at the same time.
If you prefix the class, or data-items, that's fine as well
