Hey Jacob this can work with custom code. I came up with 2 approaches that work. The first implementation takes HTML from a field value and renders it within the custom code embed. The issue you ran into was that the HTML rendered was escaped on publish. There’s a script in the page settings that reconverts the value back into HTML on load.
The second approach as suggested by @AlexN renders the HTML inside an embed and would allow you to place a unique embed code inside each item. I recommend the second approach because you’d only need to set the unique embed ID on each item instead of the entire HTML string.
