Just coming back to give my thanks for this.
It's working but is causing the product images in the collection not to display with the following message - No products found in this collection
All the products are showing as active in the collection but they just don't display...
Anyone else reported this or have you encountered this happening?
@adamtoogood Having a split banner image and text is possible. But it requires knowledge to write the markup and styles. If that's not something you are comfortable with I would suggest not doing so at this time.
