Hello
I am displaying 12 products per page (3 rows of 4) on the category listing. On scrolling down to page controls when I advance to the next page cursor position is maintained at the bottom. My client would like it to return to the top and I have tried inserting javascript to do this. It appears after returning to the top, the theme is automatically returning to the bottom of the page. What is the best way to achieve this? Thanks
