How do I remove the "Please Choose a Category Banner" from the storefront section?
Response:
There are two ways to make the banner invisible:
1) That banner has a css class, nextTopBanner. You could use css to set the display value to none in Layout/Edit Advanced Layout/CSS Addendum. 2) You could specify that the banner color and banner text color are the same as the background color (Layout/Edit Main Layout/Storefront).
