If you use your store's versions as separate online stores (so that each store version has its own product catalog, info pages, settings etc.), you may want to define unique front pages for each version to clearly differentiate between them by means of distinct design.
If you'd like to create unique designs for version-specific front pages, you will need HTML/CSS expertise. You can also have your online store's designer do it or commission the project to MyCashflow.
To define distinct front pages, you will need the Web Designer extension. The extension provides a template selector and FTP credentials.
Creating a custom front page
The version now uses the product group of your selection as its front page with its own unique template. Repeat the steps for all store versions for which you'd like to specify a unique front page.
