Add content above and below Magento product listings using the Category Description available in 1.4, then updating where the static block displays on the category page when customizing the Display Settings to include both a static block and products.
The main focus of being able to customize the content in Magento category pages was to add the ability for me to be able to have an introductory paragraph of content, but also add additional content after the product listing. Thus I was able to add a foundation of custom content to main category pages without pushing the products further and further down the page.
First you will want to create a static block that will become the footer content for a category. Once created you can then update your category to call this static block. Navigate to the Category you want to include the content below the product listing and update the display settings. Under ‘Display Settings’, select ‘static block and products’ from the Dsiplay Mode dropdown. Then select the name of the static block you created under the CMS Block dropdown.
