Answer 1

I think you want to know how access the nested dict in template

If you think I got your question

Generally, This is the way to access the nested dictionary items in dictionary.

If the iterables are getting nested further just you have to increase the forloop depth level whether it is list or dict.

Here I am giving just a generic example in my own way for your understanding

Data:

parent_dict = {1: {'A':'val1','B':'val2'}, 2:{'C':'val3','D':'val4'}}

iteration in jinja2:

{% for key,parent_dict_item in parent_dict.items() %}
   {% for key2, nested_value in parent_dict_item.items() %}
      
{{ nested_value }} 
   {% endfor %}
{% endfor %}

Answer:

val1 
val2 
val3 
val4
