Custom Tags

These are used in the product description area for creating custom tabs with your own text on the tab. The tab text comes from the text in between the delimiters.

Example:
<!--%Product Description%-->
The name of this tab is "Product Description". This is the text on the product description tab.
<!--%Custom Information%-->
This is where the next tab is created. All text from below this tag goes on the "Custom Information" tab.

All text before the first tag will be above the tabs.
