You'll want to import this CSS/SCSS change: Choices-js/Choices@1c43069

@coorasse would you mind adding a pull request to add a choices-bootstrap.scss ? I'll then bundle that into the distribution and automatically generate a .css file.

Newb here, I think this will theme the choices components to look like bootstrap is that correct? If so, how do I do that? I'm not sure where to put this choices.scss file and how to make it work. Thank you for any help.

Hi @Xon , in order to generate the final CSS, you'd need to include also bootstrap, because it requires bootstrap scss variables. I don't think it can be bundled together. But you can bundle the scss!

Silly question, but what are the minimal other files you need to import/use to compile this? I'm a bit of a noob with sass and so far I've learned that if I import, I get two copies of everything so I try to 'use' when possible but the order & such escapes me here.
