You can link pages, items and sections to the navigation bar as long as you are linking a URL (internet address) inside eBay. That means you cannot add links to external shops or sites.
How to add links?
- In the Create Design tab choose your template and then click on navigation.
2. Once you click on one of the pencil icons you could edit a navigation tab. An pop-up will open and you will be able to change the title of the button and add a URL to an eBay destination.
The destination could be a link to an item, seller etc.
At the end click on save (button right) and the design will be updated immediately.
