Global
Your website can also have Global content.
Global content is used in places where you want the content to stay the same from page to page. To access global content, click on the Pencil icon in the sidebar.
Defining global content
If you want a navbar to have global content, copy its Content names into the Global content and place the content you'd like there.
This content will override any content in the component whose Content you copied.
Multilingual
Most of the time, globals are used for components don't change that much from page to page.
However, when you translate your website, you probably want to translate the content inside of the navigation and the footer.
In that case, you'll need multilingual global content.
