The options listed on this page allow you to choose the way a product shows on the department and category pages.
By choosing "Enabled," the Headers that you upload to Store Manager will only show on the pages that show all the products from a certain section.
For a brand, it will show the header for the URL .../shop/brandname, but will not show for the URL .../shop/women/brandname.
For a department, you may want to have a link under your TOPS section that shows all tops, and you want to show an image in the header, but you do not want any images on the other links in that section.
Here the VIEW ALL department has an image above the products:
But the other sub-departments do not show an image, only products.
