Hi there,

I’m sorry, my expression wasn’t clear enough.

What I mean is that you need to make the left-side categories extend beyond the browser height size. There are two issues with exceeding the size: firstly, without adding CSS syntax(overflow-y: scroll), it won’t be visible, and secondly…

After adding the CSS syntax, you can view the overflowing categories by scrolling. However, since you didn’t scroll the BODY element first, the thumbnails of those categories that extend beyond the browser won’t be loaded.

So, if you add more categories and make them exceed the height of the browser, you will understand the issue I mentioned.
