Webpack + IE 11 not working with library

[roma-formio]

Hi Andreas, maybe you can help me. I'm using vanilla-picker library on my application, but have troubles when trying to import Picker. All browsers work fine, only IE 11 throw error like

SCRIPT1006: Expected ')'

When trying to use the library with tag <script> all works fine.
Would be great if you can have a look into that.

Hello!

Without seeing the output code, this is only guessing, but it may be because IE doesn't support some particular ES6 feature. Possibly related SO question.

Do you have Webpack transpile your code, for example using Babel? Make sure it also transpiles dependencies (i.e the vanilla-picker module).

Any luck?

Please update to v2.9.2. The module is now transpiled before release (which I've learnt is the best practice).
