Derek,
Your new Menu snippet works great. I created a superfish-style menu
using
a list of groups, like so:
object MenuWidgetEx {
def apply(groups:List[String]) = new MenuWidgetEx(groups,
MenuStyle.HORIZONTAL, JsObj()) render
def apply(groups:List[String], style: MenuStyle.Value) = new
MenuWidgetEx(groups, style, JsObj()) render
def apply(groups:List[String], jsObj: JsObj) = new MenuWidgetEx
(groups, MenuStyle.HORIZONTAL, jsObj) render
def apply(groups:List[String], style: MenuStyle.Value, jsObj:
JsObj) = new MenuWidgetEx(groups, style, jsObj) render
}
class MenuWidgetEx(groups:List[String], style: MenuStyle.Value, jsObj:
JsObj) extends
MenuWidget(LiftRules.siteMap open_!, style: MenuStyle.Value, jsObj:
JsObj){
override def render :NodeSeq = {
def buildMenu(group:String) = <lift:Menu.builder group={group}
expandAll="true" top:class={style.toString} />
head ++ <div>
{for(group <- groups) yield {buildMenu(group)}}
</div>
}
Someone should redo the MenuWidget snippet to handle your
new Menu.builder construct, so it doesn't have to be subclassed.
