You can create links on your website navigation to take visitors to another website. This is handy, for example, when you want to link to an outside voter information page.
In the Page editor, Click the Additional Page Options Link
Navigate to the Alternate URL field and enter the full address to the website you want to link to. Include the https://www.
Click the New Window checkbox so the link opens in a new window.
Save your page
Next you need to re-generate your website navigation.
In the Admin Navigation go to Site Setup and select Site Navigation from the dropdown menu.
If your page is already showing, click Save Navigation. Or else add the page and then click Save Navigation.
