I often get asked how to have menu items open in a new window or tab, also known as target=”blank”. This feature is supported in WordPress by default, you just need to know how to enable it. Open “Screen Options” in the Appearance > Menus page and click on the “Link Target” checkbox under “Show advanced menu properties”.
Your links will now have a “Open link in a new window/tab” option, simply check it to let the link open in a new window or tab.
The “Open link in a new window/tab” option will also be available at Pages and Category menu items.
