You can alter the display of the Customize pages that get displayed when the user clicks on the Edit Settings
icon in the widget's title bar.
You do this by creating a IBM® WebSphere® Portlet Factory model that displays the editable widget settings and sets the widget's parameters from the user's inputs.
Using a different model for customization
If changing the look and feel of the Customize page does not provide you with the changes you want to implement, you can create a WebSphere Portlet Factory model that implements the intended customization.
