batch

batch

The batch filter "batches" items by returning a list of lists with the given number of items. A second parameter can be provided and used to fill in missing items:

{% set items = ['a', 'b', 'c', 'd', 'e', 'f', 'g'] %}

<table>
{% for row in items|batch(3, 'No item') %}
    <tr>
        {% for column in row %}
            <td>{{ column }}</td>
        {% endfor %}
    </tr>
{% endfor %}
</table>

The above example will be rendered as:

<table>
    <tr>
        <td>a</td>
        <td>b</td>
        <td>c</td>
    </tr>
    <tr>
        <td>d</td>
        <td>e</td>
        <td>f</td>
    </tr>
    <tr>
        <td>g</td>
        <td>No item</td>
        <td>No item</td>
    </tr>
</table>
