Expand description

Batch items.

This filter works pretty much like slice just the other way round. It returns a list of lists with the given number of items. If you provide a second parameter this is used to fill up missing items.

<table>
  {% for row in items|batch(3, '&nbsp;') %}
  <tr>
  {% for column in row %}
    <td>{{ column }}</td>
  {% endfor %}
  </tr>
  {% endfor %}
</table>
