Hello,
I want to disallow nested lists like:
- List item
- Sub item
or:
1. List item
- sub item
in the editor. I found this ticket: [Prevent nested Lists · Issue #31 · ProseMirror/prosemirror · GitHub](https://github.com/ProseMirror/prosemirror/issues/31) but I could not get it working. Both OrderedList and BulletList use NodeKind.list\_item. So my idea was to allow only Text or Paragraph nodes in NodeKind.list\_item.
But contains() in ListItem:
```
export class ListItem extends Block {
get kind() { return NodeKind.list_item }
get contains() { return NodeKind.text }
}
```
returned an error:
> RangeError: Wrap not possible
Any ideas? Thx a lot

It might be easier to make list items contain only paragraphs (though that will also require giving paragraph a new, specific kind). To make list items contain text you’ll have to make them textblocks (i.e. you’ll need a new class that inherits from `Textblock`).

I would definitely prefer to use paragraphs.
So I have to:
1. Giving the Paragraph-class a new kind ? Currently it has NodeKind.block
2. Setting List Item class to contains only Paragraph-class
?
Can you may give a rough example plz?

I think you should be ok if you
- Define a variable `paragraphKind` which is `new NodeKind("paragraph", [NodeKind.block])`.
- Use a subclass of the default `Paragraph` which has a `get kind() { return paragraphKind }` getter.
- Use a subclass of the default `ListItem` with has a `get contains() { return paragraphKind }` getter.
(I realize this is awful, and am working on a more usable and powerful system for this stuff right now, which will hopefully make it into 0.7.0.)
