This plugins broken when the version of IE below 10

[Jed5]

When I use it which version is 1.13.2 in IE8 or 9,
IE console shows 1 errors:
Unable to get undefined or null referenced property "toggle" in bootstrap-select.js (30,3)
IE8 and 9 isn't compatible with Element.classList. so how to use it in IE 8 and 9? can you give some suggestions

Thanks

Bootstrap 4 doesn't support IE8 or 9 either, so if you're moving to the 1.3 version for BS4 support, there's probably more things you're going to run into.

I'll need to add a classList polyfill at some point (which can then be removed in v2), but for now, check out https://github.com/eligrey/classList.js/.

Released in v1.13.4!
