To enable AJAX-like technology use the following menu parameters:

        var dmAJAX = 1;                 // enables AJAX-like support
        var dmAJAXCount = 2;      // number of all submenus in the menu

Each .js file must contain menuItems variable for the submenu in the following format:

    var menuItems = [
           [text, link, icon1, icon2, tip, target, itemStyle, submenuStyle, jsFileName],
    ];

Where jsFileName - .js filename on the server that contains menuItems variable for the submenu.
