String dropdown: multiple values and checkboxes

Current behavior
In entity data type ou dropdown from string, we can select multiple values per field.
In string dropdown there is no such option. Only one value can be stored.

Also, the option for checkboxes would be great.

Expected behavior
Multiple values selectable.

I believe the multiple values should be fairly easy to do.

Adding checkboxes would probably not serve the intended purpose, since a core functionality is preserving order. With checkboxes, it would either be sorted in the order of the checkboxes or we would need to create quite a complex UI to order the checkboxes as well, which I don't think we would go for ATM.

Well... Order and checkboxes do not mix, so when a user chooses the checkbox option, the order is set by the options list.
The same thing would apply to a radio option for the single selection.
It's basically an addon for user interface, but still needs some insight from who created the form.

multiple values is possible using the new picker input types in 17.03 :)

Still in beta, but most things such as this work - needs some docs though...

ATM there is no checkboxes UI, but there is another issue for that #3179
