<td>
item1<br> item2<br>
</td>
could be done just with a listview too:
<td>
<span wicket:id="list"><span wicket:id="label" /><br></span>
</td>
those spans shouldn't be in your way, and you could even set the
rendering of the tags off.
And you can nest listview as deep as you want.
But I probably don't understand what you mean? :)

I don't think so, or at least it's the step beyond that that I'm not
seeing. My tries with a ListView gave me a repeated set of
<td>item</td> blocks, (using a Label for the item), but I can't see
how I can generate something like:-
<td>
item1<br>
item2<br>
..
item10<br>
</td><td>
item11<br>
item12<br>
..
</td>
I think that if the original 1-row format isn't kept, I might be able
to do something similar, where the key might be to explicitly re-map
the input list into a list of 'horizontal' lists, then use a series of
<tr>'s enclosing <td>'s, each enclosing a single item, but that didn't
seem to be all that simple/clean and I wondered if I was missing
something obvious... (Maybe I need to investigate extending
ListMultipleChoice or it's parent, and see where that gets me.)

First a Form. The a ListView. And for each row a Label and a CheckBox
component? As the checkboxes paths are unique for each row, you should
have no problems there.
Doesn't that work for you?

Hi,
I'm currently trying to 'mirror' a quick & dirty JSP page in Wicket
& wondering how best do a particular thing...
I've got a list of Services, with basically a String ('name') and a
boolean attribute ('free'). There are 90-odd of these, and I need to
display them as checkboxes in a set of columns. The Q&D JSP method
puts them in a table, with a set of checkboxes making up a column in a
<td>...</td>, as below...
String generateServiceTable(List services, int colSize, String
listName) {
int cols = (services.size() / colSize) + 1;
StringBuffer sb = new StringBuffer();
sb.append("<table ><tr>\n");
int rows = 0;
for (int i = 0, ; i < services.size(); i++) {
Service service = (Service) services.get(i);
if (rows == 0) {
sb.append("<td valign=top width=\"" + 100 / cols +
"%\">\n");
}
rows++;
sb.append("<input type=\"checkbox\" name=\"" + listName +
"\" value=\"");
sb.append(service.getName());
sb.append("\"");
if (service.isFree()) {
sb.append(" checked");
}
sb.append(">");
sb.append(service.getName());
sb.append("<br>\n");
if (rows == colSize) {
sb.append("</td>\n");
rows = 0;
}
}
sb.append("</tr>\n");
sb.append("</table>\n");
return sb.toString();
}
so I get a
a1[] a11[] a21[] a31[] ...
a2[] a12[] a22[] a32[] ...
...
a10[] a20[] a30[] a40[] ...
effect, but I'm having difficulty working out a good/clean/simple way
of achieving the same result with Wicket.
(Note that using the same name on the checkboxes results in them
behaving in the same way as a multiple-choice list does, in terms of
what the browser dispatches, at least.)
I had this all working happily, using a ListMultipleChoice, so I've
got the 'surrounding' form/model, etc, it's just how best to do this
that's unclear...
