#1. First, add a Video Block under Accordion (You can add video under, next to, or any position that you want).

#2. Install Squarespace ID Finder and find the ID of Accordion Block – Video Block.
In my example, we will have:
- Accordion Block: #block-yui_3_17_2_1_1717399220695_38419
- Video Block: #block-yui_3_17_2_1_1717399220695_39083

#3. Use this code to Page Header Code Injection (the page where you use Accordion)
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.7.0/jquery.min.js"></script>
<script>
jQuery(document).ready(function($){
$('#block-yui_3_17_2_1_1717399220695_39083').appendTo('#block-yui_3_17_2_1_1717399220695_38419 li:nth-child(2) div.accordion-item__description');
})
</script>

#4. Result
