summary: Helper function to return the list of alternatives for a source
---
type: function

version_added: 2.0

body:

Given a source this function returns the list of all [Alternatives
:ref](../../../content/alts/) that the source exists as.  It does not include
fallbacks unless `fallback=True` is passed.  If no source is provided all
configured alts are returned.  If alts are not configured at all, the return
value is an empty list.

This returns only the list of alt short IDs.  Access to the configured name
of the alt within the project config is not available.  Databags should be
used to provide alts with a human readable title.

## Example

```html+jinja
<p>Other languages:
<ul>
{% for alt in get_alts(this) %}
  <li><a href="{{ '.'|url(alt=alt) }}">{{ alt|title }}</a></li>
{% endfor %}
</ul>
```
