# Builder Fields & Acai Attributes
## Field Types (`data-field-type`)
The builder uses `data-field-type` attributes on HTML elements to define editable areas.
| Type | Description | Returns |
|------|-------------|---------|
| `textfield` | Single line text | String |
| `headfield` | Heading text (generates `_tag` variable for semantic tag: h1-h6) | String |
| `textbox` | Multi-line text | String |
| `wysiwyg` | Rich text editor (HTML output) | HTML string |
| `link` | URL field (already includes slashes) | String |
| `upload` | Single image/file | Array: `[0].urlPath`, `[0].info1` (alt), `[0].info2-4` |
| `uploadMulti` | Multiple images | Iterable: `item.urlPath` |
| `list` | Dropdown (fixed options or from table) | String or foreign key num |
| `multiv2` | Repeatable group of fields | Array of objects |
