In the admin panel go to Appearance->Menus. Then click on “Custom Links.”
This will slide open the box to enter a new custom link. In the URL field place the “#” character. In the “Link Text” field put in the name of the menu link. In this case we are creating a menu link called “Testimonials.” Then click the “Add to Menu” button.
The new menu item will be added to the menu as a custom link. When you click on this link on the website, it will not go anywhere.
