I would recommend to add a custom tag as_chunk. I think it makes the code prettier and more readable.

# app/templatetags/my_tags.py

from math import ceil
from django import template

register = template.Library()

@register.filter
def as_chunks(lst, chunk_size):
    limit = ceil(len(lst) / chunk_size)
    for idx in range(limit):
        yield lst[chunk_size * idx : chunk_size * (idx + 1)]


# app/templates/your-template.html

{% load my_tags %}

...

{% for chunk in elements|as_chunk:6 %}
  

    {% for element in chunk %}
      

        {{ element.name }}
      
    {% endfor %}
  
{% endfor %}
