public class AccordionLayoutContainer
extends InsertResizeContainer
implements HasActiveWidget

A layout container that manages multiple content panels in an expandable accordion style such that only one panel can be expanded at any given time (by default). Each panel has built-in support for expanding and collapsing. Note: Only ContentPanel's and subclasses may be used in an accordion layout container. Each content panel should be created with AccordionLayoutContainer.AccordionLayoutAppearance to produce the expected accordion panel look and feel. The AccordionLayoutAppearance must be created using the GWT.create(Class) method to enable GWT class substitution, as illustrated in the following code snippet.

Code snippet:

    AccordionLayoutContainer con = new AccordionLayoutContainer();
    AccordionLayoutAppearance appearance = GWT. create(AccordionLayoutAppearance.class);

    ContentPanel cp = new ContentPanel(appearance);
    cp.setHeadingText("Accordion Item 1");
    cp.add(new Label("Accordion Content 1"));
    con.add(cp);
    con.setActiveWidget(cp);

    cp = new ContentPanel(appearance);
    cp.setHeadingText("Accordion Item 2");
    cp.add(new Label("Accordion Content 2"));
    con.add(cp);

    cp = new ContentPanel(appearance);
    cp.setHeadingText("Accordion Item 3");
    cp.add(new Label("Accordion Content 3"));
    con.add(cp);

    Viewport v = new Viewport();
    v.add(con);
    RootPanel.get().add(v);
