Thanks a lot for the sample. Fixed for next version. For now, please make the following change;
in SapphireMenuRenderer.jar

Code: Select all

...
protected void encodeSubmenu(FacesContext context, AbstractMenu menu, Submenu submenu, boolean megaMenuChild) throws IOException{
	ResponseWriter writer = context.getResponseWriter();
        String icon = submenu.getIcon();
        String label = submenu.getLabel();
        int childrenElementsCount = submenu.getElementsCount();
        boolean megaMenu = false;
        /****** Please see these lines *******/
        if(submenu instanceof UISubmenu) {
            Object mega = ((UISubmenu) submenu).getAttributes().get("mega");
            
            if (mega != null) {
                megaMenu = Boolean.parseBoolean(mega.toString());
            }
        }
        /*************************************/
        if (megaMenuChild) {
            writer.startElement("span", null);
            writer.writeAttribute("class", "layout-megamenu-submenu-text", null);
            writer.writeText(label, null);
            writer.endElement("span");
        }
To provide new jar please use mvn clean install -P distribute command
