Cleditor：如何将工具栏放在两行中

Question

我需要Cleditor的工具栏分为两行，我的代码是：

var list = [txtDescripcion, txtRecomendacion, txtEfecto];
var controls_ = "bold italic underline strikethrough subscript superscript | font size 

var options = {
    height: 172,
    width: 309,
    controls: "bold italic underline subscript superscript | font size " +
                "  | color highlight | bullets numbering |" +
                " alignleft center alignright justify | undo redo | " +
                " cut copy paste pastetext";
}

$.each(list, function (i, elem) {
    var editor = this.cleditor(options);
    editor[0].focus();

谢谢你的帮助！
