# Footers

Footers are specialized sections that appear at the bottom of every page in the storefront. They follow the same structure as regular sections — same folder layout, settings files, entry points, and composables — but are placed in the template configuration's `footer` slot instead of in page sections.

### Differences from Sections <a href="#differences-from-sections" id="differences-from-sections"></a>

| Aspect                | Section               | Footer                                    |
| --------------------- | --------------------- | ----------------------------------------- |
| Type                  | `SECTION`             | `FOOTER`                                  |
| Mandatory content     | None                  | None                                      |
| Mandatory design      | None                  | None                                      |
| Placement             | Inside template pages | Template configuration `footer` slot only |
| Used in page sections | Yes                   | No                                        |

Unlike [Headers](/site-themes/develop-site-themes/headers.md), footers have **no mandatory settings** — you are free to define any content and design editors you need.

### Template Configuration <a href="#template-configuration" id="template-configuration"></a>

Footers are referenced in the template's `configuration.ts`, not in page sections:

**Default footer** (built-in):

```
footer: { type: 'default', id: 'footer', showcase_id: '1' }
```

**Custom footer** (your own section with type `FOOTER`):

```
footer: { type: 'custom', id: 'my-custom-footer', showcase_id: '1' }
```

When using `type: 'custom'`, the referenced section must exist in the `footers/` directory and have `type: 'FOOTER'`.

### Validation Errors <a href="#validation-errors" id="validation-errors"></a>

| Error                                                           | Cause                                     | Resolution                                     |
| --------------------------------------------------------------- | ----------------------------------------- | ---------------------------------------------- |
| *"Footer section must have id 'footer' when type is 'default'"* | Default footer must use the id `"footer"` | Set `id` to `'footer'`                         |
| *"Custom footer section must exist in footers directory"*       | Referenced custom section not found       | Create the section in the `footers/` directory |
| *"Custom footer section must be of type 'FOOTER'"*              | Custom section exists but has wrong type  | Set the section's type to `'FOOTER'`           |
