Bug? I guess.

What is the current behavior?

Form onChange is called only on attachToForm but it doesn't called when you remove an input.

working example: https://codesandbox.io/s/formsy-vnfvm?file=/src/index.js

I would love to have the functionality to sort the selected Images via Drag and Drop. I think it could be solved by an ReorderableListView relative easily.

We should add tabs under Configuration in https://docs.cxjs.io/widgets/menus and support both Menu and MenuItem.

For a long time I thought this was impossible to do without writing toString/fromString functions for your custom types, but I just realized that you can make it work by instead using the list index of the options as the "value", and then in the onChange decoder use that index to retrieve the item from the passed in options list.

Here's a demo: https://ellie-app.com/7253Q8THR2xa1
