re-render?

[bknill]

The component doesn't seem to update when the data changes. Any way to force an update?

it uses shallow compare. you should change your data in immutable way or update it like:

<Nestable items={[...items]} />

While you can use it as a hotfix till you start sticking to immutability, it can lead to some performance issues if you have more that 100 items.
