How Do I Create Configurable Portlets?

A configurable portlet is one that has portlet preference that either other administrators or even end users can modify.

A portlet preference is a property in a portlet that can be customized by either an administrator or a user. Unlike regular portlet properties (locale, name, description) that pertain to a portlet, a portlet preference allows you to define preferences on how a portlet performs or what it displays.

To see a portlet with configurable preferences:

Select Portals under Portal Management in the top Menu in the Editor pane.
Expand the Library in the Portal Resource tree, and select All Portlets.
Select the RSS News Feed portlet.
Click the Edit button next to each preference to see the field that you can edit.
