Is it possible to add a product’s reviews to a collapsible row on the product page when using the theme Dawn?
Sorry you are facing this issue, it would be my pleasure to help you.
Welcome to the Shopify community! 
Thanks for your good question.
Please share your site URL,
I will check out the issue and provide you a solution here.
I am looking to do the same thing in our new site. Would love help in figuring that out.
I figured it out. I’m using the Judgeme app for reviews, so I just needed to add the last 4 lines to my product code:
{%- when 'collapsible_tab' -%}Hello - I’m also trying to do this in my shop, and can’t seem to figure out where to copy/paste this code. I know this is an old thread, but do you mind walking through the steps you took? My product template is in .json and won’t accept this when I copy/paste. And Judge.me help/support seems confused at what I’m asking help with. Thanks!
I just contacted Judge.me support. They were very helpful.
Thanks - I also contacted them and even sent a link to this post, and they weren’t helpful. Hopefully, the person I’m messaging with passes it along to someone in tech support. Thanks for replying!
How do you make judge me review widge a collapsible row? I’m having the same problem and the code for work for me

Ok but what did they do to help you with that and how do I contact them.
It would be good if Shopify or Judgeme would sort this so we could do it ourselves. My theme doesn’t get automatic updates since this needs to be done manually by Judgeme. So each time I do the theme update myself, I need to contact Judgement to add the review widget back into the collapsible row .. then ensure they tweak it so it opens and closes properly.
It would be great if Judgeme added it as a feature we can sort ourselves. If everyone could vote for the suggestion I made it would be great https://feedback.judge.me/suggestions/538498/add-judgeme-review-widget-to-shopify-product-collapsible-row
The link on my suggestion should have been https://sinister.co.nz/products/la-riche-directions-dye-midnight-blue) … check it out if you want to see how the collapsible row works. Anytime I update my shopify theme I have to contact Judgeme to go through setting up the collapsible row again .. it is such a pain. If Judgeme added it as a feature my shopify theme would automatically update.
