Yireo has developed a Magento extension called ByAttribute. The module allows you to add a list of manufacturers on a page. To use ByAttribute you will need to purchase this commercial module in our Yireo Shop. This video-tutorial takes you through the steps to put ByAttribute to use within a CMS page.
The following code is used during the tutorial. However, for more information on how to write the right XML-code of your choice, we would like to refer you to our tutorials section.
&t;reference name="left"> <block type="byattribute/options" name="left.byattribute.options"> <action method="setAttributeValue"><string>manufacturer</string></action> </block> </reference>
