If necessary, specify what type of portlet this is:
Narrow: Narrow
portlets can be added to narrow or wide columns. Columns extend to fit portlet
content; therefore, if you choose narrow for a portlet that produces wide
content, your portal might look awkward.
If you created this portlet from a portlet template that creates
narrow portlets or if you are editing an existing a narrow portlet, you
can change it to a Wide portlet but not to a header, footer, or content
canvas portlet.
Wide:
Wide portlets can be added only to wide columns.
If you created this portlet from a portlet template that creates
wide portlets or if you are editing an existing a wide portlet, you can
change it to a narrow portlet but not to a header, footer, or content
canvas portlet.
Header:
Header portlets can be added to communities,
community templates, and
experience definitions
to change the branding of these objects by replacing a banner at the top
of the page (so that it differs from the top banner displayed by the main
portal).
You cannot change this setting if you created this portlet from
a portlet template that creates header portlets or if you are editing
an existing header portlet.
Footer:
Footer portlets can be added to communities,
community templates, and
experience definitions
to change the branding of these objects by replacing the banner at the
bottom of the page (so that it differs from the bottom banner displayed
by the main portal).
You cannot change this setting if you created this portlet from
a portlet template that creates footer portlets or if you are editing
an existing footer portlet.
Content Canvas:
Content canvas portlets can be added below the top banner on community
pages that include a content canvas space (specified in the page
layout). Content canvas portlets can display across the entire width
of the page or across one or two columns. You cannot add more than one
content canvas portlet per page.
You cannot change this setting if you created this portlet from
a portlet template that creates content canvas portlets or if you are
editing an existing content canvas portlet.
If this is a narrow or wide portlet, specify whether this portlet is a community-only portlet:
If you want to allow users to add this portlet to My Pages or community pages, choose For My Pages or Community pages.
If you want to allow users to add this portlet only to community pages, choose For Community pages only.
If this is a narrow or wide portlet and you do
not want to display the title of this portlet when it is added to a page,
select Suppress Portlet's title bar.
Note: If this portlet includes preferences or help, suppressing
the title bar will make these features unavailable in the portlet.
