Select2 accepts themes, an example is bootstrap4.

To configure it, you need to include a new css file and add the theme option when starting select2.

<link rel="stylesheet" href="/path/to/select2.css"> <link rel="stylesheet" href="/path/to/select2-bootstrap4.min.css">

$('select').select2({ theme: 'bootstrap4', });

The settings could look like this:

# accept str too SELECT2_CSS = ( "/path/to/select2.css", "/path/to/select2-bootstrap4.min.css", ) SELECT2_THEME = `"bootstrap4"`

I am willing to develop this option if it is valid.
