# Custom Gradebook Columns

API for adding additional columns to the gradebook. Custom gradebook columns will be displayed with the other frozen gradebook columns.

#### A CustomColumn object looks like: <a href="#customcolumn" id="customcolumn"></a>

```js
{
  // The ID of the custom gradebook column
  "id": 2,
  // When true, this column's visibility will be toggled in the Gradebook when a
  // user selects to show or hide notes
  "teacher_notes": false,
  // header text
  "title": "Stuff",
  // column order
  "position": 1,
  // won't be displayed if hidden is true
  "hidden": false,
  // won't be editable in the gradebook UI
  "read_only": true
}
```

#### A ColumnDatum object looks like: <a href="#columndatum" id="columndatum"></a>

```js
// ColumnDatum objects contain the entry for a column for each user.
{
  "content": "Nut allergy",
  "user_id": 2
}
```
