Thanks for implementing the List it helped with a lot of other items. :+1:

What do you think of #4 ? Do you want to finish it on your own or should I tackle it?

My timeline for this project would look something like this:

• Finish Select until new year (either you or me)
• Create demo website in first week of January

Sure, I will come back to it. I will try to update the PR before the end of the week.

The crashes and strange behaviors of the components which change the DOM via the material-components-web.js is a bit of concern. We need to check if this is the case or not. If we can't use the script it will be a challenge. (I left a comment in the Slider issue)
