Please see the solution mentioned in below link. It suggested to make the topmost label in the harness as a hyperlink using span tag . You can apply css to it , if u don't want the hyperlink . This will work and you won't have to run the window.scrollTop() script explicitly.

Hi James,

You can also try the below approach:

1. Create a property. Make sure this property is not visible.

2. Add this property at the top of the screen (top of the section).

3. On the button which you are using to add product you can configure on click event at the end to set the focus to this new property created.

Hope this helps!

Regards,

Vikash
