I think the idea is that the backend already iterates over the data and spits out for example a ul with a li per faq item. You edit the template the backend uses so that the vue annotations are also produced, which in theory is easier than changing the backend code.
EDIT:
Previous HTML outputted by for loop in backend template:
<ul>
<li>
<h2>Question 1</h2>
<p>Answer 1</p>
</li>
<li>
<h2>Question 2</h2>
<p>Answer 2</p>
</li>
</ul>
<ul>
<li>
<h2>
<button v-on:click="expanded = 1">
Question 1
</button>
</h2>
<p v-if="expanded === 1">Answer 1</p>
</li>
<li>
<h2>
<button v-on:click="expanded = 2">
Question 2
</button>
</h2>
<p v-if="expanded === 2">Answer 2</p>
</li>
</ul>

You pass data into it as json. Or load it from external source as json
I don't have a lot of experience with Vue, but I don't follow. You include Vue.js from CDN in a `script` tag, and then just add the `v-for` and `v-if` annotations to your HTML? How does Vue get the data, to properly iterate over it in `v-for` or check in `v-if`?
I'm really curious because I feel I'm missing some piece of puzzle here.
