Hi there! me again. :)
Found another small bug. On DESKTOP it works fine but on certain tablet or phone, I noticed this issue.

If you see the picture above link, sub categories (when you click to expand) shows up slightly to left side of the main category. And on the phone, because main category 'Clothes' is already flushed to left end, first letter of sub-categories are cut off.
I think if you can move indent toward right instead of left on sub-categories, it'll fix the issue. :)
