Thanks a lot Andrea, that did work. Now i get only markup of visible items.
My Solution looks now: <code> ListViewEnclosurePage.html <!DOCTYPE html> <html xmlns:wicket="http://wicket.apache.org";> <head> <meta charset="utf-8" /> <link href='http://fonts.googleapis.com/css?family=Yanone+Kaffeesatz:regular,bold' rel='stylesheet' type='text/css' /> </head> <body> <div> <ul> <wicket:enclosure child="foo"> <li wicket:id="foo"> <span wicket:id="bar">[Content]</span> </li> </wicket:enclosure> </ul> </div> </body> </html> ListViewEnclosurePage$MyListView.java public static class MyListView extends ListView<String> { public MyListView( String id, List<? extends String> list) { super(id, list); } @Override protected void populateItem(ListItem<String> item) { Label label = new Label("bar", item.getModel()); item.add(label); if (item.getIndex() == 1) { item.setVisible(false); } } } </code> Thanks for your support Per > Gesendet: Donnerstag, 08.
