[Lift] Hidden field in form

[wapgui]

Hi,

is there an equivalent in lift to the hidden input filed used in
forms. The SHtml.hidden is only for functions not for parameters, the
value is always true. I want set the hidden input via javascript.

Is there also a parameter for setting the name of the form itself?

Here the code:

object smlink extends RequestVar(Full(""))

var fp = new Widget()

  def show(xhtml: NodeSeq): NodeSeq = {
    val temp =
      if (smlink.isEmpty || smlink.open_!.length == 0) "" else
"Received: " + smlink.open_!

    bind("fp", xhtml,
      "color" -> hidden({() => fp.color}),
      "title" -> text(fp.title, fp.title = _) % ("size" -> "10") %
("id" -> "title"),
      "url" -> text(fp.url, fp.url = _) % ("size" -> "56") % ("id" ->
"url"),
      "items" -> select((1 to 9).toList.reverse.map(v => (v.toString,
v.toString)),
                        Empty, fp.items = _),
      "submit" -> submit("Send", () => {
        Log.info("Submitted ")
        smlink(Full(fp.title))
      }),
      "link" -> <div>{temp}</div>
    )
  }

generates this:

<form method="post" action="/">
        <input name="F1142516722376UOU" type="hidden" value="true" /><br />
        <label for="title">Title</label>
        <input size="10" name="F1142516722377UCO" type="text" value=""
id="title" /><br />
        <label for="url">URL</label>
        <input size="56" name="F1142516722378IZS" type="text" value=""
id="url" /><br />
        <label for="items">Items</label>
        <select name="F1142516722379K2S"><option value="9">9</
option><option value="8">8</option><option value="7">7</option><option
value="6">6</option><option value="5">5</option><option value="4">4</
option><option value="3">3</option><option value="2">2</option><option
value="1">1</option></select><br />
        <input name="F1142516722380W2M" type="submit" value="Send" />
        <div></div>
        </form>

Cheers
Torsten
