I’m still trying to wrap my head around the way Prosemirror is structured. Sorry if I’m going about this in completely the wrong manner.
I would like ProseMirror to recognize the structure that we have in our documents. They are currently represented as just two separate paragraph tags enclosed within a div with a special attribute and class.
In my HTML, I have a DOM structure like so:
```auto
```
In my schema definition, I defined the NodeSpec? like so:
```auto
org_property: {
defining: true,
priority: 60,
content: "paragraph{2}",
parseDOM: [{tag: 'div.orgProperty[data-label="property-label"]'}],
toDOM() { return ["div", {"data-label": "property-label", "class": "orgProperty"}, 0] }
}
```
Currently, when prosemirror parses this structure, it will turn the HTML it into the following:
```auto
:Name:
Item
```
It basically just strips out the enclosing div. I’m using the [ProseMirror dino example](https://prosemirror.net/examples/dino/) as a starting point… My thought was that I needed to create a NodeSpec defining the enclosing div. The div will always have two paragraph tags within. Is there anything obvious that I’m doing incorrectly?

The code you pasted looks good, but it seems the parser isn’t matching that node type for some reason. Did you confirm that the schema you are using is the right one, and has that node type in it?

Here is a screenshot of the schema object right before the dino example creates the `EditorView()` instance.
I see `org_property` is in the listing of nodes. Is there something special that I need to check on the `org_property` NodeType?
The constant `dinoSchema` is used directly after my `console.log(dinoSchema)` line to create and assign `window.view`, so I’m pretty sure the `EditorView()` is using the same schema with the correct NodeType.

You failed to specify a way in which the `org_property` node can actually be part of the document—it doesn’t appear in any content expression, and it’s not part of any group that does appear in content expressions.

Interesting… So just because I added a node to the schema doesn’t mean that it’s allowed within the document?
So it order for a `org_property` to appear, it must be in a content expression under another node in the schema or assigned a group which must also be used in another content expression?
Would it be correct to modify the `doc` node’s content expression to match a `org_property` node?

Yes, if the top level is the only place you want this to appear, doing something like `"(block | org_property)+"` in `doc` would work.

I just encountered the same issue.
I tried the schema
```auto
new Schema({
nodes: addListNodes(schema.spec.nodes, "paragraph block*", "block")
.append({org_property: {
defining: true,
priority: 60,
content: "paragraph{2}",
parseDOM: [{tag: 'div.orgProperty[data-label="property-label"]'}],
toDOM() { return ["div", {"data-label": "property-label", "class": "orgProperty"}, 0] }
}}),
marks: schema.spec.marks,
doc: {
content: "(block | org_property)+"
}
})
```
But the dom structure
```auto
```
is stilled parsed into
```auto
:Name:
Item
```

Your `doc: {content: "(block | org_property)+"}` text is just going to get ignored (`doc` doesn’t mean anything in a schema spec). You probably want to replace the `doc` node spec under `nodes` instead.

Oops. I am new to prosemirror. But I like it. Thank you.
