From the Organizations list, select your organization. In the sidebar, under Customize, click Sidebar.
Customize the default sidebar items shown to users in this organization. Users can override these settings from their personal sidebar settings.
The page provides two modes via radio buttons:
Uses the platform default sidebar configuration. All navigation items are shown.
Allows you to toggle visibility of individual sidebar navigation items. When selected, a list of all navigation items appears with checkboxes. Some items are marked as "unhideable" and cannot be removed.
Note
Individual users can override these organization defaults from their personal account settings.
