Border less portlets or gadgets can help to create page composes of several component looking to be seamlessly in the same component. Can this be done at a portlet configuration level or must it be by creating a global skin for the portal (in this this would prevent configuring some portlets to be borderless by the side of normal portlets).
Thx
When you edit your page, edit the portlet and on the "Portlet Setting" tab uncheck "Show Info Bar".
You can see that right from the home page (everything is a portlet and none have the borders)
