For individual elements, where you don't mind having all markup
already in the source of the page:
Hiding:
ajaxrequesttarget.appendJavaScript("document.getElementById('" +
component.getMarkupId() + "').style.display = 'none';");
Showing:
ajaxrequesttarget.appendJavaScript("document.getElementById('" +
component.getMarkupId() + "').style.display = '';");
Otherwise, put everything in the panel, and update the whole panel
whilst setting the visibility flags of the child components:
class MyPanel extends Panel {
private WebMarkupContainer normalView;
private WebMarkupContainer detailedView;
private AjaxLink showDetails;
private AjaxLink hideDetails;
MyPanel() {
.......
add(showDetails = new AjaxLink("showDetails") {
onClick(AjaxRequestTarget t) {
normalView.setVisible(false);
hideDetails.setVisible(true);
detailedView.setVisible(true);
setVisible(false);
t.addComponent(MyPanel.this);
}});
The rest is left as an exercise to the reader.
