I had customized the HTML widget (with css) to hide the widget title but then I realize the problem. As an administration, I will not be able to edit the widget as the "edit/delete" button is within the title.
The jive-widget-header css class is used for both design-time and run-time display of the widget headers. I'm not a css buff, but I noticed that the jive-widget-handle css class is only present when the page is in "widget design mode", if that makes sense. So I wonder if there's a way to ensure that css style is visible even when the jive-widget-header style is hidden?
