Answer 1

You could try to create a custom template filter, that would return a list of list of 3-items.

Quick attempt :

@register.filter
def splitByThree(data):
    return [l[i:i+3] for i in range(0, len(l), 3)]

And then in your template :

{% load splitByThree %}

{% for list in data|splitByThree %}

{% for item in list %}
{{ item }}
{% endfor %}

{% endfor %}
