Customizing Information Page Tabs for the Site
Public and Private Tabs
As a site administrator, any information page tabs that you create and configure for an object type can be Set Public or Set Private when you right-click the tab name. If a tab is Set Public, it is available to all users in your site, in every organization.
For example, if you create a new tab on a document information page, by default it is Set Private, and only you can see it. But if you right-click the tab and select Set Public, the tab is then available on all document information pages for all users in your site.
Note the following information regarding public and private tabs:
Set Private is the default setting.
Private tabs display in gray.
Public tabs display in blue and include a public tab icon identifying that any changes made to the tab will be seen throughout your site.
For any tabs Set Public by a site administrator, the tab title displays in italics for end users and organization administrators to indicate that the tab cannot be modified. Any tabs created by a site administrator can only be managed by a site administrator. This includes:
renaming the tab
changing or reordering the tables within the tab
deleting the tab
Site administrators can see only the out-of-the-box information page tabs and any tabs set public at the site level. Site administrators cannot manage information page tabs created by individual users or see information page tabs set public by an organization administrator, as organization-level tabs can differ by organization.
Show or Hide Tabs on Subtypes
Determine if information page tabs that you create display on information pages for objects that are subtypes. For example, if you have a part subtype called electrical part, and you create a new tab on part information pages, determine whether the new tab should also display on information pages for electrical parts. Right-click the tab name and select Hide On Subtype or Show On Subtype.
* 
New tabs created on information pages for objects that are subtypes are not inherited by parent types. So if you created a new tab on information pages for electrical parts, it will not display on part information pages.
