Externally-Linking Navigation Tabs
Navigation tabs obviously link to their respective pages. Now you can create a tab that links to an external website or any custom URL that you wish. For example, you could add a tab that links to a sister website. Real estate agents could link to a third-party MLS search page. Or you could even link to a specific URL within your website (ex categories, products, etc). To create a new page, simply follow the same steps as normal, and select "custom URL" from the page type dropdown.
