Data files with html content - eleventy

Question

I'm making a nice simple html page using external data... here's the bit that's causing me grief:
<section class="faq_main">
{% for section in faq.sections %}
<h3>{{ section.heading }}</h3>
{% for question in section.questions %}
<article class="faq_question">
<a id="hide_{{ section.code }}_{{ question.code }}"
href="#hide_{{ section.code }}_{{ question.code }}"
class="hide"><span class="faq_toggler">+</span> {{ question.question }}</a>
<a id="show_{{ section.code }}_{{ question.code }}"
href="#show_{{ section.code }}_{{ question.code }}"
class="show"><span class="faq_toggler">-</span> {{ question.question }}</a>
<div class="details">
{{ question.answer }}
</div>
</article>
{% endfor %}
<p> </p>
{% endfor %}
</section>
... and the matching faq.json file:
{
"sections" : [
{ "heading" : "Section the first",
"code" : "gn",
"questions" : [
{
"question": "What do questions need?",
"code" : "1",
"answer": "An answer"
},
{
"question": "Is this also a question?",
"code" : "2",
"answer": "Yes, it is"
},
{
"question": "Is this junk data?",
"code" : "a",
"answer": "Yes"
},
]
},
{
"heading": "Another section",
"code" : "f",
"questions": [
{
"question": "Can I have html in my answer?",
"code" : "2",
"answer": "<ul>\n<li>First, json needs newlines escaped to be newlines</li>\\n<li>Eleventy seems to 'sanitize' the string</li>\\n</ul>"
},
{
"question": "question b",
"code" : "b",
"answer": "answer b"
},
{
"question": "question c",
"code" : "or",
"answer": "answer c"
},
]
}
]
}
.... and the rendered text for the answer in question is:
<ul> <li>First, json needs newlines escaped to be newlines</li>\n<li>Eleventy seems to 'sanitize' the string</li></ul>
Do I have any options here? Is there a way to allow [even a subset of] html elements into the page?
(and yes, the CSS does the clever show/hide descriptions using the '+'/'-' symbols - all that side of things works just lovely)

Answer 1

It should work by inserting the symbols directly into the quotes in the json. Use Non-breaking spaces for indentation, and unicode points for dots.
Otherwise, the framework is broken.

Answer 2

Change {{ question.answer }} to {{ question.answer | safe }}
(see https://www.11ty.dev/docs/layouts/#prevent-double-escaping-in-layouts - it's clear, once you understand what it's saying :) )
