body:

In some situations it can be very useful to generate a unique ID in templates.
This is particularly useful when creating templates for the [Flow
:ref](../../../../flow/) system and you need unique IDs for the DOM.

## Example

```html+jinja
{% set id = get_random_id() %}
<div id="{{ id }}">
  <button data-target="{{ id }}" class="toggle">Hide This</button>
</div>
```
