I was looking to make a really simple FAQ page that consisted of questions in h2 headers and answers under the h2s in simple paragraphs. I could not find this exact solution so after a bit of research I made my own.

jquery:

$(document).ready(function(){
$(".faq h2").nextUntil("h2").slideToggle();
$(".faq h2").click(function() {$(this).nextUntil("h2").slideToggle();});
});

HTML:

<div class="faq">
<h2>This is question 1</h2>
<p>This is the answer</p>
<p>This is the answer</p>
<h2>This is question 2</h2>
<p>This is the answer</p>
<p>This is the answer</p>
<p>This is the answer</p>
<h2>This is question3</h2>
<p>This is the answer</p>
</div>

Leave a comment if you find it handy!
