# Section Widget

> Create section headers and organize content in templates

The Section Widget displays section titles and organizes content into logical groups. Section widgets are always visible to the end user.

<Warning>
  **Summary widgets MUST be the first widget created in every sheet**
</Warning>

## Example Code

```json theme={null}
{
  "type": "sheetTemplateWidgets",
  "attributes": {
    "type": "section",
    "label": "",
    "referenceId": "",
    "collapsed": false,
    "visibleIf": null,
    "description": null,
    "references": null,
    "authorNotes": null,
    "referenceImage": null
  }
}
```

<ParamField path="type" type="string" required>
  Must be "section" - defines the widget type
</ParamField>

## Best Practices

<Tip>
  * Use descriptive section labels that clearly indicate the content within
  * Include relevant code references in the `references` field
  * Consider using collapsed sections for advanced or less commonly used options
  * Always create a Summary section as the first widget in every sheet
