Once the Product Matrix has been built you’ll need to configure the Product Matrix URL.
The url should look something like this:
http://www.mysite.com/Home/ProductMatrix/mid/400/Default.aspx
Next, add the category id to the end of the URL for the product matrix you want to display.
The URL should look something like this:
http://www.mysite.com/Home/ProductMatrix/mid/400/Default.aspx?categoryid=1
You can now use this URL to link to the matrix from another page on your site using a button or hyperlink.
