Most layout containers can contain children of any content type. However this widget must have children of type AccordionPane. The reason for this is that each child must have a title bar with a label and a control. AccordionPane acts as a wrapper around ContentPane and adds the additional features for title and control. This widget contains children of type AccordionPane which can contain any content including other layout widgets. When the widget is first built one pane is visible and the other panes are stacked beneath it with only their controls showing. When the control icon is clicked the first pane will close and the clicked pane will slide open producing an effect like an accordion being played hence the name . Display Examples HTML Markup Examples Notice that the Pane Control Icon is different depending on whether the pane is open or closed. Only one pane may be open at a time. The user can click anywhere on the pane control to open it not just on the icon .
