Recursion in jinja template - html

Question

I need to provide a JSON formatted information from a CMS into a web page.
There may be deep nested structures in the page input like:
{
"input": [
{
"header": "sample header text",
"description": "sample description text",
"content": {
"json": {
"children": [
{
"type": "paragraph",
"children": [
{
"text": "sample child text "
},
{
"href": "https://myorg/tilasto/kony",
"type": "link",
"title": "Linkki ",
"children": [
{
"text": "sample child text"
}
]
},
{
"text": "sample child text"
}
]
},
{
"type": "table",
"children": [
{
"type": "table_body",
"children": [
{
"type": "table_row",
"children": [
{
"type": "table_cell",
"children": [
{
"type": "paragraph",
"children": [
{
"text": "sample text"
}
]
},
{
"type": "table",
"children": [
{
"text": "sample text"
}
]
},
{
"type": "paragraph",
"children": [
{
"text": "sample text"
}
]
}
]
},
{
"type": "table_cell",
"children": [
{
"type": "paragraph",
"children": [
{
"text": "sample text"
}
]
}
]
}
]
}
]
}
]
}
]
},
"references": [
]
}
}
]
}
How can I recursively do the same thing as in the below HTML?
{% for tiedote in input %}
<br>
<h2> {{tiedote.header}}</h2>
<p> {{tiedote.description}} </p>
{% for children_list in tiedote.content.json.children %}
{% for child in children_list.children %}
<p> {{child.text}} </p>
<a href="{{child.href}}">
{% for chil in child.children %}
<p> {{chil.text}} </p>
<a href="{{chil.href}}">
{% for chi in chil.children %}
<p> {{chi.text}} </p>
<a href="{{chi.href}}">
{% for ch in chi.children %}
<p> {{ch.text}} </p>
<a href="{{ch.href}}">
{% endfor %}
{% endfor %}
{% endfor %}
{% endfor %}
{% endfor %}
{% endfor %}
Also href may be present in some level of the input, how can I check if it is present or not?
Updated: In order to use macro (as in answer) in jinja template do I need to install django-macros or would there be any other means for that?
