Portlet headers contain the name of the portlet and any customize or edit defaults links. Portlet borders delineate each portlet in a region. You can choose whether or not to display portlet headers and borders.
The following example shows the same region, first with portlet headers and borders displayed, then with them hidden.
To
display or hide portlet headers or borders, you must have at least
one of the following privileges:
Manage All privileges on the page group to which the page belongs
Manage privileges on the page
Manage global privileges on All Pages
Because portlet headers contain the customize link, if you hide them, users will not be able to customize the portlets in the region. Users will still be able to edit the portlet defaults by editing the page.
Go to the page with which you want to work.
