The Categories tab is used to assign an associated eBay Store Category to a Zen Cart Store Category. This defines the default eBay Store Category for each Zen Cart Store Category.
To connect categories in your Zen Cart store to categories in your eBay store, open the Categories Tab of the plug-in.
Click on a Zen Cart store category to display the children of the category or, if there are no children, a control for selecting the eBay store category to map to the Zen Cart store category will be displayed. The selected eBay store category will be used as the default eBay store category when listing products in the Zen Cart store category on eBay.
