There are two ways to set skin:

• Passing skin name to constructor (the second argument);
• Using setSkin method.

To set skin with constructor you should call dhtmlXMenuObject with the second argument, which contains skin name:

    var menu = new dhtmlXMenuObject("parentId", "dhx_skyblue");

If you just initiate contextual menu and have no parent object yet, you can pass null as the first argument:

    var menu = new dhtmlXMenuObject(null, "dhx_skyblue");
    menu.renderAsContextMenu();

Also you can easily cnahge skin “on-the-fly” using setSkin method:

    var menu = new dhtmlXMenuObject("parentId");
    menu.setSkin("dhx_skyblue");

Available skins are:

dhx_skyblue (the default one)	dhx_blue	dhx_black
