Ah, perfect! Thx! Incidentally, I simplified in two places by instead of doing this:
List.range(0, rowNum).foldLeft(Util.emptyNodeSeq)((ns, i) => { }) doing this: List.range(0, rowNum).flatMap(i => { }) (simlar change in the row function) -harryh On Aug 18, 3:52 pm, Ryan Donahue <donahu...@gmail.com> wrote: > You could do something like this. > > Snippet: > > def func(xhtml: NodeSeq): NodeSeq = { > val foos = Foo.findAll(...) > val rowSize = (S.attr("rowSize") openOr "10").toInt > val rowNum = (foos.size + rowSize - 1) / rowSize > List.range(0, rowNum).foldLeft(Util.emptyNodeSeq)((ns, i) => { > val start = i*rowSize > val end = start+rowSize > ns ++ bind("list", xhtml, "row" -> row(foos.slice(start, end)) > _) > }) > } > > private def row(foos:List[String])(xhtml: NodeSeq) : NodeSeq = > foos.foldLeft(Util.emptyNodeSeq)((ns, foo) => ns ++ bind("foo", > xhtml, "name" -> foo.name)) > > Then your template can use table/tr/td or it could just use floating > divs that wrap over when necessary: > > <table> > <lift:MyPage.func rowSize="10"> > <tr> > <list:row> > <td><foo:name/></td> > </list:row> > </tr> > </lift:MyPage.func> > </table> > > OR > > <lift:MyPage.func> > <list:row> > <div class="cell"><foo:name/></div> > </list:row> > </lift:MyPage.func> > > For an empty NodeSeq that works in the foldLeft I've had to create the > following.
