The HTML markup for an InputText widget looks like this.

<textarea id="textbox1" ></textarea>

You can initialize the widget with the following jQuery script. The options set in this script create an input that only allows users to enter four lines of text.

<script type="text/javascript">
    $(document).ready(function () {
        $("#textbox1").wijinputtext(
        {
            maxLineCount: 4
        });
    });
</script>

The markup and script featured here results in the following live widget. Enter text in the widget and notice that it only accepts four lines.
