Navigation not only helps users access content throughout your intranet, it helps them to understand what information is available on the site.
There are two main types of navigation available for intranets: Global Navigation for every page, and Site Navigation for a specific site.
Navigation is one of those things that's easy to create, but hard to do right. Given that you're creating navigation for your users, we highly recommend getting users involved in the process. We have some great blog posts to help you on your journey.

Global Navigation appears on every page of your intranet, typically along the top of the page, as shown in the example below. The navigation style may vary, and can include a simple click on a name in the navigation to land on the page, drop down menus, or mega menus with categories and lots of choice.
To edit the Global Navigation, click the edit pencil on the right side of the top navigation, as shown in the image below.
If you just want to edit the navigation, mouse over the area and follow the information for Edit Navigation.
If you want to add a new section to the Global Navigation, click the large + sign on the right. You'll be presented with the choice of three options for your new section, as follows. Note that it isn't possible to convert one type of navigation to another (e.g. change Single Menu to Mega Menu); you would need to create a new menu section of the type you want, then delete the unwanted type.
After making your changes, when you're satisfied with your new menu item, click Save Menu at the bottom of your screen.
As the name suggests, a Site Menu only appears within a specific Site, on the left side of the page. You can customize this menu to include all kinds of different links.
When you Add a Site to your intranet and start to build it, a basic Site Navigation is automatically added for you. If you Add a Page to your Site, you'll need to take the additional step to add that page to your Site Navigation by editing the navigation.
If you're having problems seeing all of your menu to edit it, click Ctrl and the minus sign to reduce the size of your text on your screen. After you've finished editing, click Ctrl and 0 to return it to 100%.
