Sass mixin for select2 customization, is there one already?

Question

css

Hello! For dropdown lists I use Select2
To change the appearance I set the theme:

$(".js-example-theme-single").select2({
    theme: "example"
});

And after I set the styles through (sass):

.select2-container--example {
    /*
    и тут задаю дочерним элементам стили
    */
}

This method takes about 30 minutes in time and, as for me, causes code duplication, each time I write the same selector names, with the exception of .select2-container--example, if more than 1 drop-down list is used on the page ...
There is an idea to do mixin... where to set only the modifier class .select2-container--example and styles, the question itself. Am I reinventing the wheel? Are there ready-made mixins for this task? Thank you!

Answer 1

You probably need to set the theme globally $.fn.select2.defaults.set("theme", "classic");
And in css to use a more general selector?

Answer 2

Isn't it possible to immediately edit the included CSS file of this plugin?
I converted this file to SASS, edited it, and it already gets into the general compiled CSS. Everything is working.
