I’ve used a few HTML-Codes from a different website, and it works fine to use parts of it, but not more than around 2K rows in the HTML-sections before it becomes laggy. I want to add more parts, but it just won’t let me edit them further after pressing save. The lag makes it impossible to edit. Anyone know what to do?
Hey! Just sharing an updated note here in case this helps 
Adding large amounts of HTML directly inside the editor (like very long code blocks) can affect performance and make editing laggy.
For better results, we recommend keeping HTML sections smaller or moving heavier code to Custom Codes (Head/Body) instead of placing everything inside elements.
This helps keep the editor responsive and easier to work with.
