Build your own sidebox
Zen Cart has a number of built in sideboxes; other sideboxes are available in the sideboxes section of the Zen Cart plugins library. But even with this number of options, some storeowners find their custom requirements necessitate building a sidebox. That’s how the plugins library got populated, after all!
The easiest way to build a new sidebox is to start with the Blank Sidebox.
Experiment with content and layout options until you have something that’s perfect for you. Then please consider contributing your work to the Plugin Library so that others may benefit from your efforts.
