My product's description is too long, because of that, i really want to add something like read more button... the content can be extended only if someone click on the read more button?

This is the one we use. Put the things you want hidden in your click here for more button in between <div class="block-content"> and the first </div>

<div class="collapsible">
<p style="text-align: center;"><button data-toggle="collapse" data-target="#demo">Click here for more...</button></p>
<div id="demo" class="collapse">
<div class="block-content">
</div>
</div>
</div>

Hope this helps!
