Can you just make your 1d list look like a 2d list to the ListView?
// this make a 1d list to look like a 2d list
class FoldingList extends AbstractList<List<String>> implements
Serializable {
List<String> inputList;
int width;
int size;
FoldingList(List<String> inputList, int width) {
this.inputList = inputList;
this.width = width;
this.size = inputList.size() / width;
}
@Override public List<String> get(int index) {
return inputList.subList(width*index, width*(index + 1));
}
@Override public int size() {
return size;
}
}
public HomePage extends WebPage {
List<String> dataList = new ArrayList<String>(Arrays.asList(new
String[]{
"Item1", "Item2", "Item3", "Item4", "Item5", "Item6"
}));
FoldingList list2 = new FoldingList(dataList, 2);
ListView listView = new ListView("columnList", list2) {
@Override protected void populateItem(ListItem item) {
@SuppressWarnings("unchecked")
List<String> row = (List<String>) item.getModelObject();
item.add(new Label("column1", row.get(0)));
item.add(new Label("column2", row.get(1)));
}
};
add(listView);
}
<table border="1" style="border-collapse: collapse;">
<tr wicket:id="columnList">
<td wicket:id="column1">column1</td>
<td wicket:id="column2">column2</td>
</tr>
</table>
